Detailed explanation-1: -The idea is to write programs in high-level language, but instead of compiling it (translating) into machine language, it translates it into an intermediate code. This intermediate code is executed by an interpreter known as Virtual Machine.

Detailed explanation-2: -An interpreter translates source code into object code one instruction at a time. It is similar to a human translator translating what a person says into another language, sentence by sentence. The resulting object code is then executed immediately. The process is called interpretation .
