Once your java code compiled, compiled code(.class) can be executed on any os platform...if your question is HOW..it is interesting which deals with bytecode conversation

Because of JVM , JVM can be installed in any Operating system.Write once and execute anywhere(ANY OS) your code.

because java has a own runtime environment it's program is not depend on operating System. c and C++ does not have run time environment ,c & C++ program are Depend for run on OS.

Previously, most of the programs written in any language have had to be recompiled or rewritten for every other computer platform. Means, you have to either change your code or recompile it when you change the platform (i.e. windows or UNIX or Mac OS etc).JAVA comes with its greatest advantage that you...

Previously, most of the programs written in any language have had to be recompiled or rewritten for every other computer platform. Means, you have to either change your code or recompile it when you change the platform (i.e. windows or UNIX or Mac OS etc).JAVA comes with its greatest advantage that you only have to write and compile your code once. The Java on any platform will interpret the compiled byte code (.class file) into instructions understandable by the particular processor using either interpreter or JIT compiler. JVM uses both the interpreter and JIT compiler. Note: JIT(Just In Time) do not do code compilation but the byte code compilation to platform language (Instruction set) So we can say if we have JVM available for any platform, the onetime compiled code will work on it using the WORA feature of Java i.e. Write Once Run Anywhere. read less

I think your question is "Why Java is called platform independent?"- Java lets you compile source code (written in java) on one platform say Windows and the same compiled code can run on machine with any other platform(be it unix , linux etc) having a JVM running on it.

I think your question is "Why Java is called platform independent?"- Java lets you compile source code (written in java) on one platform say Windows and the same compiled code can run on machine with any other platform(be it unix , linux etc) having a JVM running on it. And if your question is - Why Java is platform independent? Answer - Its the beauty of open source Java , that it does not discriminate between platforms. :) read less

because every program gets compiled forming a byte code file that can be interpreted on any platform having JAVA runtime environment JRE.

First of all, a platform is anything on which a program is run(in lay man term). A platform is either the machine itself, or a primitive kernel or a fully developed OS. Languages can be platform dependent or independent. Dependent means its executable code and source code varies from platform to platform. That is to say that the programmer has to make some changes in the code if it has to run on other platforms. Languages like C are platform dependent. Platform independent means that the code remains the same irrespective of the platform involved. Java has something called a virtual machine called JVM or Java Virtual Machine. What happens in case of Java is that the JVM once installed on any platform like windows or OS X can run the java code without any alteration. The JVM acts like a virtual platform on which the code is executed. As the platform being JVM remains constant throughout all platforms Java programs can run on any platform irrespective of the real platform. If you want to know the detailed process then it is here: Java source code written in the high level java is first converted to something called the javabyte code. This byte code is not readable by the original platform, but only the JVM can read it and then it executes it. This is the primary reason why Java is much in use even today. read less

Because once you compile Java code the binaries / class file generated are not machine dependent instead they contain byte code which at the time of execution translated to respective machine code by the JVM(Java virtual machine)

One of the major features of java includes that why java is called platform independent language. Before understanding this feature we need to know about – Javac – compiler that converts source code to byte code. JVM- interpreter that converts byte code to machine language code. As we know java is both compiler & interpreter based language. Once the java code also known as source code is compiled, it gets converted to native code known as BYTE CODE which is portable & can be easily executed on all operating systems. Byte code generated is basically represented in hexa decimal format. This format is same on every platform be it Solaris work station or Macintosh, windows or Linux. After compilation, the interpreter reads the generated byte code & translates it according to the host machine. . Byte code is interpreted by Java Virtual Machine which is available with all the operating systems we install. so to port Java programs to a new platform all that is required is to port the interpreter and some of the library routines. Source code -> javac ->Universal byte code Universal byte ->jvm/java -> execute them on a particular machine. Another reason the makes Java a Platform independent language is the elimination of undefined or architecture dependent constructs. Therefore java is called platform independent language. read less
