Expert Solution
Step 1: Introduction
In Java, the name of the file must match the name of the public class it contains. If the class is called MyClass, the file should be named MyClass.java. It should also be saved in a directory structure that matches the package name.
For example, if the package is called com.example, then the directory structure should also be com > example. This is the convention for Java, and it helps prevent naming conflicts for classes.
