You can create one or more classes in single file. Only one
class may be declared as public. This is your Optional.

If you declared a class as public, your file name should be
the save of your class name.

Public class can be accessible from other applications.
Example, your applet code can be run in a web browser. This
public class may execute other classes in the same file.

If you declared two classes as public, your file name will
be what?

Note the Example :

class First {
// Some codes here
}

public class Second {
// some codes here
// In core, your main method should be here.
// You have to save the file as Second.
}
