Question

if you have a class defined in separate files, and change the main program, which files need to be re-compiled?

Answer 1

The application and implementation files must be recompiled if a class is declared in separate files and the main program is changed.

What version of the class file is it?

We designate the class file's version as M.m, where M stands for the major version and m for the minor version. Note: Compiler developed by lower version. High version JVM may run class files, but higher version compiler created. Class files cannot be run by JVM versions below that.

What do you name the process of joining the implementation and application files to create an executable file?

Linking is the process of combining the implementation and application files to create an executable file.
