Moreover, which compiler is best for Java?

The two most known Java compilers are:

• Javac: This compiler is developed by Oracle. This compiler needs to be installed along with any IDE's (except Eclipse IDE) or to run Java code in terminal.

Also to know, how does compiler work in Java?

In Java, programs are not compiled into executable files; they are compiled into bytecode (as discussed earlier), which the JVM (Java Virtual Machine) then executes at runtime. Java source code is compiled into bytecode when we use the javac compiler. The bytecode gets saved on the disk with the file extension .
