Every Java program is first compiled into an intermediate language called Java bytecode.
The JVM is used primarily for 2 things:
1. The first is to translate the bytecode into the machine language for a particular computer,
2.The second thing is to actually execute the corresponding machine-language instructions as well.
The JVM and bytecode combined give Java its status as a "portable" language – this is because Java bytecode can be transferred from one machine to another.

Machine language is OS dependent
Given the previous information, it should be easier to figure out an answer to the original question. Since the JVM must translate the bytecode into machine language, and since the machine language depends on the operating system being used, it is clear that the JVM is platform (operating system) dependent – in other words, the JVM is not platform independent.
Almost all JVMs are implemented in software. However, a JVM is anything that interprets Java bytecode in a manner that complies with the JVM specification, and there are some hardware-based JVMs as well.
A Java processor is the implementation of the Java Virtual Machine (JVM) in hardware. In other words the bytecodes that make up the instruction set of the abstract machine become the instruction set of a concrete machine. These are today the most popular form of a high-level language computer architecture.
