Devaka ExamLab Diagnostic Question 3

[J desai]

       class SuperClass{
           static void printMe(){
                System.out.print("super context ");
           }
      }
      
      public class SubClass extends SuperClass{
           public static void printMe()throws ArithmeticException{
                System.out.print("sub context ");
           }
           public static void main(String argv[]){
                SuperClass sc=new SubClass();
                sc.printMe();
           }
      }   

My confusion is that printMe() is a static method and is inherited by the subclass. I know static methods cannot be overridden. But how can the static method with same name as super class be declared. why doesn't compiler give a Name Clash error.

Hi J desai,

Welcome to JavaRanch

See JLS Section 8.4 Classes section for details.
It is allowed in subclass to use same static method name of super class.

[Ankit Garg]

When you declare a method with the same signature as the method of the super class, it is called hiding. See Overriding Vs Hiding for more details...

[Harsh Pensi]

Also to make things confusing, you need to follow the rules of overriding while "hiding" a static method in a subclass

Hi Desai,

Is the Devaka ExamLab working fine for you? I have installed it in windows XP. I have a hard time to figure out why the clicks for Diagnostic exam & practice exam 1,2,3 links are
not working.

The only link that is working is final exam.


Please share your experience.
Thanks
Saritha

I think you asked this before here. Try reinstalling the application. I also installed it and there were no problems...
