6. What is the output of this program?
   

   import java.util.*;
       class genericstack 
       {
           Stack  object = new Stack ();
   	public void push(E obj) 
           {
               object.push(obj);
   	    }
   	    
   	public E pop()
           {
               E obj = object.pop();
   	    return obj;
   	    }
       }
       
       public class Output
       {
           public static void main(String args[])
           {
               genericstack  genericObj = new genericstack();
               genericObj.push("Interview");
               System.out.println(genericObj.pop());
           }
       }

8. Why are generics used?

1. 1. Generics add stability to your code by making more of your bugs detectable at compile time

   
   
   

   2. Generics make code more fast

   
   
   

   3. Generics add stability to your code by making more of your bugs detectable at runtime

   
   
   

   4. Generics make code more optimised and readable

   
   
   

   5. None of these
