A compiler translates the code written in one language to some other language without changing the meaning of the program.
It is also expected that a compiler should make the target code efficient and optimized in terms of time and space..
Java compilers include the Java Programming Language Compiler (javac), the GNU Compiler for Java (GCJ), the Eclipse Compiler for Java (ECJ) and Jikes..
There are a few different steps the compiler takes to correctly compile the code.
First it takes your code and turns it into a sequences of tokens.
This is a process called lexing which is a fancy term for turning your code into tokens.
Each token contains symbols, numbers, and letters that make sense to the compiler..
An interpreter is also a software program that translates a source code into a machine language.
However, an interpreter converts high-level programming language into machine language line-by-line while interpreting and running the program..

A compiler is a translator that converts the high-level language into the machine language.
High-level language is written by a developer and machine language can be understood by the processor.
Compiler is used to show errors to the programmer..
A compiler is a software that converts the source code to the object code.
In other words, we can say that it converts the high-level language to machine/binary language.
Moreover, it is necessary to perform this step to make the program executable.
This is because the computer understands only binary language..
