Compiler vs interpreter a compiler is a computer programor a set of program that transforms source code written in a programming language into another computer languagethe target language. Same is the case with java or any other programming languages. The compiler and interpreter both translates the higher level language programs, the difference lies that a compiler compiles the source code into an executable machine code whereas an interpreter interprets each instruction and executes it without producing any. A compiler generates machinedependent assembly code which can then be assembled and linked to into the appropriate machine opcodes to allow the program to execute. The compiler is a translator that simply convert the program from one language to another language, from highlevel language to machine level language.
