Defining classes in different files

[Shikha Upadhyaya]

Should public classes of a single application be defined in separate .java files ?

[John Jai]

Yes. Else you will get an error. So if you have 10 classes that are declared public, you will end up with 10 java files.

Oh ok thanks Is there any specific reason for the same?

See this recent thread - http://www.coderanch.com/t/555184/java/java/Why-name-public-class-should

The answer is yes and no

yes....for the inner public classes defined inside the top class file

no....for the classes defined outside the class that was defined in its own file(class name and file name are the same)

Are you sure you have “yes” and “no” the right way round?

[Harsha Smith]

public class OuterClass {
	 int x;
	public class InnerClass{
		
		
	}
	
	public class AnotherInnerClass{
		
  }

}


class X { //X is top level class but not defined in its own file. can be abstract or final
	
	public class A{//inner classes can be public
		
		
	}
	
	public class B {
		
	}
	
	
	
}

Harsha - thank you for the good example
