Q:

What is Interpreter in Java?

Answer

  • An Interpreter is a program that reads in as input a source program, along with data for the program, and translates the source program step by step.


 


The Java interpreter decodes each lines bytecode and runs a series of machine instructions for that bytecode. The JVM takes the byte code and generates machine code. The byte code is compiled to machine code, and the machine code is executed.
