The universe of programming languages is large and full of exciting concepts! 

Though, when we talk about programming languages, there is no chance that the name of java will not pop into your mind.

Similar to C++, this highly popular object-oriented language comes with some advancing features and versatile functions. There would be hardly any programmer, who doesn’t know about this multi-purpose language.

Although programmers use this language often, one doubt they may have in their mind is; is java platform independent or not?

Well, if you too have this question in mind, you are on the right blog post!

Get inside the technicalities of java by knowing the nits and grits about it.

So, without any further ado, let’s get started!

About Java

Java is a multi-purpose language and touted as the object-oriented language which is simple, quick and easy to understand language. The language was first developed by James Gosling in 1995.The language is touted to be secure, portable, dynamic with so many amazing features. This supports multiple-functionality and helps the users in executing various programs by learning various essential topics like has a relationship in java.

What do you know about the platform independent?

Before getting started with the question of is java platform independent or not, let’s first understand what platform independent means?

A platform is defined as any kind of software or hardware where your individual programs will run. In java, we basically work on the java runtime platform which is a validate platform for the given language.

The operating system generally  is in the form of windows or mac or linux. To run any program on the machine, you should convert it to the prescribed machine language so that your machine can understand the program. As in java, your source code will not be converted into its machine code, it will first convert these codes into the byte codes also called as the jvm.

Here, the platform independent means that all the programs that will be executed are independent and will align as per the operating system. All these programs will be executed in a fast and more convenient manner.

Platform dependent and platform independent

Though these terms may seem the same they are quite different in several ways. Using the java virtual machine, a byte code can be understood by any language. That is why this code is known as platform-independent.

However, java virtual machines are touted as different from each platform, it is called as the platform dependent. The important points to note here is:

  • In java, all programs will be compiled into their byte codes and all these byte codes will be platform independent
  • These byte codes will be executed by java virtual machine which is touted to be the platform dependent
  • Though, java itself is considered as platform independent language
  • Any machine which is executing the byte code will need java virtual machine

How does a program execute in java?

Well, this is a question that is often asked by so many programmers. To execute a code in java it is first written and then the below-mentioned steps are taken into account:

  • Instead of any kind of machine native code, the compiler in java will produce the a.class file in its bytecode [ but it works differently from C compiler]
  • The resultant bytecode will nor be machine executing and requires the interpreter for the running of the computer. The JVM takes this interpreter to execute different bytecode
  • The software will be executed to offer you the intended result
  • The compiler in this case will create the OSdependent.exe file which is then used with both C or C++

How is java platform independent?

When we talk about java being the platform independent language, we can say that the bytecode produced by this language can be run on the variety of your operating systems. In fact, varied kinds of java produced bytecodes may not require JVM for its running.

Then , the operating system too will have no impact on it. You will be able to write or execute different kinds of codes on the platform till the time you are available with the javoc platform. Here, you will be able to execute a variety of codes as long as you want.

How to execute a java code?

In Java, a compiler is there to convert programs in the form of bytecode. This code will not be the executable code. Now, any kind of another program or the operating system will help in the running of this bytecode.

When we are going to execute any kind of program or file, we can obtain it with the help of a.class file. We will also require any virtual machine in order to execute a.class file in this format. Then the JVM will be platform independent in this case.

For example; MAC or Linux will have different JVMs in the windows. They will support portability as its key feature as the code will be portable and will get executed with the help of bytecode. This will make your java language platform independent.

Compiling a code

Everytime we want to write a code, we can adhere to the syntax of the programming language. Variables, phrases or method names will be included in it. All of it will be regarded as the human literatures we read or understand.

A computer will also run the compiler to turn your source code into its machine-readable code. It will create a machine code in the format so that the CPU will understand it to execute errors.

Though, we cannot run the code of one machine in the other machine as it may vary with each operating system. Though, many of the developers or programmers may think it as something unacceptable. Java helps in the fixing of this code.

Wrapping up 

Java is a platform independent programming language which includes a variety of essential concepts like has a relationship in java.
