Exam Lab Question regarding ovverriding

[Muneeswaran Balasubramanian]

Hi to all,

I have faced the question in exam lab,the code is

class TSuper{
     protected TSuper getCls(){
          return new TSuper();
     }
     String getValue(){
          return "In Super";
     }
     public String toString(){
          return "[Super Class]";
     }
}

class TSub extends TSuper{
     public TSub getCls(){
          return new TSub();
     }
     protected String getValue(){
          return "In Sub";
     }
     public String toString(){
          return "[Sub Class]";
     }
}

public class TSample{
     public static void main(String args[]){
          TSuper ts=new TSub();
          Object ob=ts.getCls().getValue();
          System.out.println(ob.toString());
     }
}

In the above code,the getValue() in Tsuper(super class) has the default access specifier,In the TSub(Sub class) getValue has the protected access specifier,

According to the overrriding rules,

The overriding method is less restrictive than overriden method.But here the getvalue not statisfy the above condition.

Then how the above code compiles fine?.I can't understand.

Please explain the context.

Hello Munees, the access modifiers goes like this 'from less restrictive to most restrictive';

public-protected-default-private

Use it to check the program again and you will understand why it compiles.
