How can i use return statement in a method no flaming pls

Question

public class example2
public int add(int i,int j)
int k = i + j;
return k; <<<< -HERE->
public static void main(String[] args)
example2 obj=new example2();
obj.add(2,3);
System.out.println("k"+k);
Iam really really new to java programming so dont flame me
In the above program i was hoping by putting return k it would return vlaue of k to the calling object but it didnt work i had to place sys.out.println in the method and take out the return from the method for it to work
So why dosent it work and where is it returned to the k value.

The VALUE of k is returned, not the NAME k, so you cannot refer to the value by just k. To the caller, the value is obtained by evaluating the expression that calls the function. So you could do
public class example2
     public int add(int i, int j)
          return i + j;
     public static void main(String[] args)
          example2 obj = new example2();
          System.out.println(obj.add(2, 3));
}
