It means you can have something like this (more than one non-public class in a file and only a single public class in a file).
MyApp1.java


but it's illegal to have something like this (more than one public class in a file).
MyApp2.java


Hope this helps

Hi Wentao Liang,
Even in the interface also, we can not place one more public class.
It gives error like " The public type of subclass must be in its own file ". Just check this code.


public interface InterfaceTesting {
void display();


}
public class SubClassOfInterface implements InterfaceTesting{
public void display(){
System.out.println("in display Method");
}

public static void main(String args[]){
SubClassOfInterface subClass = new SubClassOfInterface();
subClass.display();

}
}


the above code give error..



package com;

public interface InterfaceTesting {
void display();


}
class SubClassOfInterface implements InterfaceTesting{
public void display(){
System.out.println("in display Method");
}

public static void main(String args[]){
SubClassOfInterface subClass = new SubClassOfInterface();
subClass.display();

}
}

will give output as ...
in display Method


reply me if i am mistake ....


Suneel.
