Platform independent means the process in which the ceratin language is capable of running on all types of operating system

I hope Im right to some extent...

Thanks...

Platform independent means the execution of the program is not restricted by the type of os environment provided...thereby, make it possible to process the program at any type of environement available.

Java is a platform independent language becoz of the bytecode magic of java. In java, when we execute the source code...it generates the .class file comprising the bytecodes. Bytecodes are easily interpreted by JVM which is available with every type of OS we install.

Whereas C and C++ are complied languages which makes them platform dependent. The source code written in C / C++ gets transformed into an object code which is machine and OS dependent. That's the reason why C and C++ languages are termed as Platform Dependent.

Platform independent means "write once run anywhere".Java is called so because it can run on any machine having the java core independent of the platform.Platform dependent is just the opposite of platform independent.The source code has to be modified according to the platform.C and C++ are so called because it's code has to be changed concerning the machine.

In Java, the source program is first compiled that generates BYTE CODE which is common for all platform. The Byte code is given to JVM (Interpreter) each platform has its own JVM. which converts byte code into machine language that can be understood by the particular machine only. Once the machine having JVM it can run any java program. In C, C++ the source program directly compiled into machine code, which is platform dependent.

platform independent means, the compiled program can be run on any operating system, JAVA is called so since it generates the byte code which can be run on any
environment.
JAVA is both platform independent and platform dependent

JAVA
platform dependent means the JVM dependent
JAVA platform independent means the compiled code can be executed any where

But here the context we are discussing is based on the code so
platform independent
means
, the compiled program can be run on existing operating system,
but not on other operating system like
C, C++ have the disadvantage that they might got executed in another system.

Platform independency means a program which can be executed on any of the operating system irrespective of the operating system on which it is compiled. Java is so called because its compiled code called as byte code/middle level code (not specific to OS) can be executed on any of the operating system.  This is possible in Java because it provides JVM with respect to each operating system and it converts the byte code to the executable code with respect to the operating system. Whereas in C/C++ its compiled code is specific to the OS
and cannot be executed on other OS. Hence C/C++ is called as platform dependent languages.

Java language supports interpreter and compiler. Compiler compiles the Java program and generates byte code of
Java program then interpreter interprets or executes Java program for getting desired output. The generated byte code is machine independant. so with byte of
Java program we can execute Java program irrespective of machine hardware,

Yes, first of all JAVA is platform independent because in JAVA we are having JVM complier it will convert source code into BYTE CODE. so, this byte code will be understandable to any type of OS. so only JAVA is said to be PLATFORM INDEPENDENT, but, in C/C++ be don't have that type of special compiler so, only it is said to be PLATFORM DEPENDENT.

A platform independent language is one which can run on any OS, No specific operating system is required
for them while dependent one is that which require specific OS to run it that is
why Java is independent of platform coz no specific requirement of OS is there
and is not platform dependent. Same reason for C and C++

Platform independent means a particular code can be run on different systems. JAVA is considered as platform independent because to run the java program on system, we only need JVM(java virtual machine). 


In C/C++ language we need complete software such as turbo c to run the program on system. That is referred as platform dependent.

If any programming language is said to be platform independent that should satisfy the following
a)The data types of the programming language must take same amount of memory space on every operating system
b)The language must have internal programs to convert one understanding form of o.s to another understanding form of o.s
for Ex:The data type integer in c,c++ takes 2 bytes in dos o.s and it takes 4 bytes in UNIX or Linux
and in c,c++ there are no internal programs to convert one understanding form of o.s to another understanding form of o.s
In the case of java the data types takes same amount of memory space on every o.s and it have the internal programs to convert one understanding form of o.s to another understanding form of o.s
due to this reasons java is said to be platform independent.

Platform independence means that we can write and compile the java code in one platform (eg Windows) and can execute the class in any other supported platform eg (Linux etc).

Platform independent itself means that which is not dependent on any platform (Operating System).
The main definition of this, is that its Compilation, Execution and Development is independent

java is called platform independent becoz, in java when a program is compiled what we get is java byte code which is not executable but highly optimized, and JVM interprets this code and converts it in to an machine language of that particular os.however in case of c and c++, code is first compiled in to an machine language of that particular os so we cannot run that compiled program on every machine that uses different platforms.
