Frequent question: Why Java is a platform independent?

Why Java is a platform independent programming language?

Java is class based and object oriented programming language. … This bytecode is sent to Java virtual machine (JVM) which resides in the RAM of any operating system. JVM recognizes the platform it is on and converts the bytecodes into native machine code. Hence java is called platform independent language.

Why Java is platform independent and JVM is platform dependent?

JVM is platform dependent because it takes java byte code and generates byte code for the current operating system. So Java software is platform dependent but Java language is platform independent because different operating system have different JVMs.

Why Java is platform independent and portable?

Java is a portable:

The Java source code is compiled in bytecode when the javac compiler is used. … This bytecode is a platform independent code because it can be executed on several platforms, that is, Write Once and Run Anywhere (WORA) .

Why pointers are not used in Java?

Why bytecode is called bytecode?

The name bytecode stems from instruction sets that have one-byte opcodes followed by optional parameters.

Is Java operating system independent?

Java is OS independent language because SAME source code will work in any OS. The issue you’re facing is about the Virtual Machine, which translates java bytecode to each OS, so, Chrome OS still does not support Java because JVM for Chrome has not been developed (yet).

Is Java is a structured programming language?

As its name suggests, structured programming is done in a structured programming language and PHP, C#, C++, Java, Visual Basic, and Python are such languages. The structured programming concept was formalized in 1966 by Corrado Böhm and Giuseppe Jacopini.

What JVM means?

Java Virtual Machine, or JVM, loads, verifies and executes Java bytecode. It is known as the interpreter or the core of Java programming language because it executes Java programming.

Who was the father of Java?

Why is C platform dependent?

C Compiler is platform dependent since it is closely linked to the OS kernel which is different for different OS. But over the years all OS’s come with pre-installed compilers and libraries that make it quite platform independent for basic programming.
