Why Select Java Programming Language

 Why Select Java Programming Language:                                                                                                                                                                                                                                                                                                                                                                               Today we can see how expenses 
 Why Select Java Programming Language

of Internet and Mobiles have been. Today, the internet has grown so much that whatever information the world wants, that information can be found on the Internet. Because of this Internet today the world has become quite small. We can talk whenever we want, or we can meet online. Almost all the things in the world are connected to the
Internet today. On the Internet today, we see not only the texts but the entire multimedia, which is everything, which can be sound, video, 
animation, graphics, etc.                                                                                                                                                                                                                                                                                                      
But the way we are able to see the Internet today, the Internet was not so long ago. Java has been a major contributor to making Multimedia various things possible on the Internet. In fact, Java was developed 
for Internet only, but today it is not only used to make the Internet 
WebPages, but today it is the easiest and useful language to develop the standalone Application Software and Distributed Application. The ease with which we can create a Distributed System using Java, we can not develop large software for Internet u
                                                                       

                                                                       

 Why Select Java Programming Language:

You must have also heard people say that computer programming is a 
 very difficult task. It's not just about everyone's bus. To become a 
Computer Programmer, MCA, Degree Level Courses like B-Level and thousands of rupees of Hardware and Software are required. At the same time, he can become the programmer whose brain works like a computer, 
that is, very fast.    Those hours can sit patiently to get a solution to any problem. etc etc.

All these things were necessary to become a good programmer, but then, 
when the Programmer learned to do programming in any language such as 
Assembly language, "C" Language '"C ++" or Cobol, Pascal, etc. This is exactly the opposite of Java. Learning in Java is as easy as learning, they rarely have to learn a language. There are just a few 
basic concepts in it, so one can easily create a program as needed and 
use it.

At the same time, he can run his application on the Internet as easily as on his own computer. We believe Programming is so hard because that's what other programs have said to us? These programs have 
Monopoly so that they can get good payment. If all people start saying that programming is a very simple thing, then will the programmers get the amount of money they are getting today for any program. Probably not, therefore, all programs say that programming is the most difficult task.
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              

Why Select Java Programming Language:

 My second Opinion...                                                                                                                                                                        People in our country think computers are so difficult because they do not get the matter written in their language. Secondly, the computer can be understood properly, when there is a good grip on English. But this is not necessary. To become a Computer Programmer, good English is not as essential as the ability to understand and explain the facts is needed.                                                             

                                                                                                                                      
The first thing to learn to program is to decide which language to start programming from. However, almost all the facts are the same in 
all languages. Like Data Types, Operators, Conditional and Looping 
Statements, etc., in almost all languages, there is a similar 
difference apart, and the method of using them is quite similar in all 
languages.

                                                                                                                                                                         If Fastly Develop a GUI Application Software, then Microsoft Company's 
Visual Basic is the simplest programming language. Thousands of 
the software has been created in this today, which are used both in the 
Personal Use and Business Use. But the lack of Visual Basic programs is that their speed is less compared to programs written in other languages ​​such as Borland C ++ or Visual C ++. The lack of this speed can be felt when a lot of Graphics has been used in the program. Like if the screen saver or any game is developed in Visual Basic, they are much lower. Therefore, those who are Professional Programmers, they never use Visual Basic for Graphics Programming.
Though learning Java is difficult to learn in comparison to Visual 
Basic, but still learning Java is very useful in many ways. The biggest feature of Java is that we can use the program developed in the World Wide Web. If you have Internet Surfing then you will have to see and listen to many animations, sounds, etc. on different websites. 
All of this work can be done very easily in Java. That is if you want to create a program that can be run on the Internet, such as online games, then you will need Java.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
The second feature of Java is that Java's program is written in a 
the special way in which we have to follow all the rules of Java 
completely. If we also neglect a small rule of Java, then we may have 
to face a lot of troubles and errors in creating a small "Hello World" 
program by compiling it.
Java has been so designed so that any errors and problems that arise 
should come at the time of the Creation of the program so that when 
the program is fully prepared, there will be no problem and Program 
Reliable, Useful and Error. Be free. And indeed Java programs are significantly more reliable than other languages. In many other 
languages, such as Visual Basic, the program does not give any errors 
until the end but generates an error at some point, which takes time 
to solve it, as it does not seem to be possible to create that 
program.        (Why Select Java Programming Language)

Why Select Java Programming Language:

 Features of Java Language:                                                                                                                   Java is not just a programming language 


but it is also a platform. When Sun Microsystems introduced Java to 
the world in November 1995, the Company's Co-Founder Bill Joy had 
given the following definition of Java:

Java is a Small, Simple, Safe, Object-Oriented, Interpreted or 

Dynamically Optimized, Byte-Coded, Architecture-Neutral, Garbage-

Collected, Multithreaded Programming Language, with a Strongly Typed 

Exception-Handling Mechanism for writing Distributed, Dynamically 

Extensible Programs. These features of Java are also called Java 

features.                                                              

                                                                       

                                                                       

Small and Simple:

Java is a small and simple language that can be easily learned. Java 
has been designed in such a way that it can be easily learned by any 
programmer and without the knowledge of the internal programming of 
computer programming, it is possible to develop more and more 
Efficient Programs.
If a program has some knowledge of any programming language, then 
he can learn to develop Window-Based Application and Internet Based 
Distributed Application (Applets) very easily and quickly.
When Java was first released, it was quite a small language. But today it has become a big language and is capable of Efficiently Developing all kinds of applications. This language is inspired by many other 

languages ​​like C / C ++, Simula, Ada, but most of it is similar to 
Coding C ++ Language.

Therefore, there is no difficulty learning a Java C / C ++ programmer. 

The good features of C and C ++ have been used in this language, 

whereas more simple concepts have been included in their languages, 

except for the confusing and typical features of these languages. As 

such, the Concepts such as Operator Overloading and Pointer of C ++ 

have been left in Java, while Advance Technique like Multithreading 

has been added.                                                        

                                                                       

 Object Oriented:

Everything in Java is defined as Object and Class, which is called 
Object-Oriented Programming System. OOPS offers us features like 
Abstraction and Encapsulation, Polymorphism and Inheritance, so that 
we can logically organize a problem in a similar way to the computer, 
the way the problem remains Actually or Physically Organized in Real 
World. Many classes in Java are already received in the form of 
Packages, which can be used by us without rewriting it.

Distributed:

There are also Execute on Java Programs Network, which is also on the 
Web. Therefore it is called Distributed Language. Distribution means that Java programs can run on any platform. We know that many types of operating systems are available today and different people use different operating systems according to their needs and wishes. If you use a Windows operating system, then Linux uses a MacOS or OS / 2. 
These are all called different platforms.

If we create a program on a Windows Based Computer language like "C" 

or Visual Basic, then those programs are easily run on all computers 

that use Windows. But if these programs are tried to execute Execute 

on Linux or MacOS, then these programs are not Execute on that 

Operating System. For these platforms, the program has to compile back 

to these platform-based computers.

While this is not so with Java. In Java, we compile the program on any the platform, they are programmed equally on all other platforms. That is, 
Java's programs can be distributed on different platforms. Therefore 
Java is called Distributed Language.

Java is designed in such a way that we can develop applications in it that can run on the Internet. Ability in this language is that it can 
share both Data and Programs on different computers on the Internet.


Java applications can access and open Remote Objects as easily as they 
open and access the Objects of Local Computer. Java provides such 
networking facility that different programs located on various 
Remote Locations can work simultaneously on the same single project at 
the same time.

Compiled and Interpreted:

Most other programs of languages ​​are either compile or are interpreted. But Java programs are also compiled and interpreted as well. Java programs are first compiled. After Java's Program Compile does not convert directly into Machine Language, it instead converts between the Source Code and Machine Code, which is called Bytecodes. 
When these Bytecodes have to run on any platform, these Bytecodes are 
interpreted according to that computer's platform and completely 
convert into Machine Code according to that machine and can be Execute 
on that platform.
                                                                                                                                                                                                                                                                                                                                                    

Robust and Safe:

Problems coming in Java programs are less likely than other languages. 
Therefore Java programs are called Robust.                                                                         Many Built-In methods have 

been developed to handle various errors generated in its compiler, and 
Java has been designed in such a way that once the error in the 
a compiled program is correct There is no possibility. All the Errors 
that are coming, they come at the same time as Program Development and 
Testing, which is handled.
In this, there are various data types for different types of errors in 
both the Compile Time and Runtime checking. It automatically releases 
the memory taken by various types of objects, so we do not have to worry 
about whether we release all memory unrequited objects and release 
their memory.

The facility is also provided for Exception Handling in Java, which we can use to solve and solve the Serious Errors, which will further protect our program. When we talk about the Internet, then security matters a lot. Java itself deals with various types of Memory 
Management and Memory Access, so it never misses Memory and access to 
Stored Data incorrectly. For this reason, Apple is not likely to get 

The virus in any computer.


Because Java does not have the facility of pointers that can access 
Directly Memory, so we can not directly access Memory of any Computer. 
Also, Java Applets never access the resources of a Client Computer, so 
Java Applets can never harm Clients computers or their data.           

                                                                       

                                                                       

Architectural Neutral / Platform Independent / Portable / Byte Coded:

Java Bytecodes can run equally on different types of processors and operating systems. Therefore it is called Architecture Neutral or 
Portable. Java programs have to be developed only once. Once it has been developed, it can be run on any platform on any computer.
Even if the operating system is changed in System Resources or 
Processor, we still do not need to make any kind of change in Java's 
program. This is one of the main reasons for Java being the most 
popular, by which we use Java for Internet Programming and run 
applications running on the World Wide Web, and interconnecting 
different computers to work on the World Wide Web Use such programs.
We can download Java Applet from Remote Computer and then run it on our computer. With this type of facility, a user receives different 
types of applications and applets at his home, which he wants to use.
Java is portable in two ways: One generates Java Compiler Byte Codes 
Instructions, which can be implemented on any computer, and is not 
dependent on Java's Primitive or Basic Data Types Machine but rather 
depend on Java Platform. That is, the size of all data types of Java 
on any computer is the same, whether we use the Java program on Pentium 
Computer, even on AMD.


Garbage Collective:

Java does not provide a program with the ability to manage memory but does the memory management itself as per the need. Therefore, there is no possibility of harm to other data during the Programmer's memory management. So this is more secure or Secure Language than languages ​​
like "C" and "C ++".

High Performance:

Java's Program Interpreted Mode has Run but still Java's Speed ​​and 

Performance is much better than other Interpreted Based Languages. 

Hence it is called High-Performance Language.

Multithreaded and Interactive:

Java provides this facility that different parts of the same software the program can be run simultaneously at the same time. Hence it is called 
Multithreaded Programming Language. For example, suppose we are hearing audio sound from a program, as well as using Scroll Bars in the same program. A Movie Clip is playing on one side in any window, 
and we are also searching for any other Movie Clip in Open Dialog Box to open any other Movie Clip. In this way, different parts of the same 
the program can be run simultaneously at the same time due to the 
Multithreaded Concept.

Dynamic and Extensible:

In Java, many versions of the same program can be maintained together. 
Therefore it is also called Dynamic Language.                                                                                                                                                                                                                                          That is, Java is a 
dynamic language. Required classes for any program in Java can be linked to Java programs when running, and as soon as the work of that class is finished, Class itself releases from Memory itself. This process is called Dynamic Process.

By java also, it can also determine which class link of the program is running in it. Also, it can link to any dynamic class or Dynamic Link 
Library in Run Time of the program and can get Run Time features. This process is also called dynamic linking.


Java also gives us the ability to use the methods of other languages ​​
in Java. These methods are called Native Methods and they do them work by running Dynamically Link in Run Time of the program. That is, 
we can increase the capabilities of Java's programs or extend by using the features of other languages ​​in Java. This process is called Java's 

Extensibility.

There are several types of Java programs:


Applications - These are programs that do not require any browser to be executed. These are stand-alone and can run on any computer. They can be run on Command Prompt.
Applets - These are programs that require a browser to run. These programs run on Web pages. An Applet Program never accesses a Local 

Machine's resource.
Servlet - These are written to enhance the Functionality of Programs 

Web Servers. They do not have a GUI.
Packages - This is a collection of Java classes that can easily be 
reused in any other Java program.
Object-Oriented Programming System is an exceptional but very powerful way of doing programming. A computer program in OOP is defined as a group of objects in which all objects can interact among themselves. That is, all the objects can transact their information with each other.

In OOPS, everything in the world is considered an object. Suppose a 
Worker Object takes Money Object from company funds Object and deposits 
it in its own BankAccount Object. If another worker uses 
DoublecheckFund Object, then the Polish Object is called.
If Java program has one of the largest features, then it is that 
Java's program can be executed on World Wide Web Pages. These programs 
are called applets. Before Java, various Web pages were written in 
HTML format only. These were such web pages, click on the hyperlink to 
see the page and see the second page then click on its Hyperlink and 
proceed further.

Second Opinion of this Question:

What's the future of Java and the Java community?
