Question

Answer 1

The .java file is the file that you write with Notepad. When you issue the javac command, the Java compiler creates a .class file. The .class file contains the byte code representation of the .java file. Byte code is the code that the Java Virtual Machine runs. So, when you compile the program, you use the .java file. When you run the program, you use the .class file.
