What does Java compiler do?
A compiler in Java translates the entire source code into a machine-code file or any intermediate code, and that file is then executed.
It is platform-independent.
A bytecode is basically an intermediate code generated by the compiler after the compilation of its source code..
What is internal Java compiler error?
The "java: compilation failed: internal java compiler error" is a type of compilation error that occurs when the Java compiler fails to generate the bytecode due to an unexpected issue or bug in the compiler itself..
The javac command reads source files that contain module, package and type declarations written in the Java programming language, and compiles them into class files that run on the Java Virtual Machine.
The javac command can also process annotations in Java source files and classes.
