Compiler
A compiler is a software program that converts the source code written by a programmer into machine language (binary code) so that the computer can understand and execute it.

Simple meaning:
Compiler = A translator that changes human-written code → computer-understandable code

There are two types of Translation

Compiler Translation:

 Compiler Translation means converting a program written in a high-level programming language into a language that a computer can understand.

Interpreter Translation :

 An Interpreter is a program that reads and executes code line by line without converting the whole program at once.

In java we use Interpreter Translation line bye line execution.
