Loop program

package com.vaannila.student;

public class MyLoop{
      public static void main(String argv[]){
      MyLoop ml = new MyLoop();
      ml.amethod();
      }

       public void amethod(){
                for(int K=0;K<5l;K++){
                     System.out.println("Outer "+K);
                     for(int L=0;L<5;L++)
                     {System.out.println("Inner "+L);}
                   }
          }
}

I was trying above example from link
http://www.jchq.net/certkey/0202certkey.htm
got output like



Outer 0
Inner 0
Inner 1
Inner 2
Inner 3
Inner 4
Outer 1
Inner 0
Inner 1
Inner 2
Inner 3
Inner 4
Outer 2
Inner 0
Inner 1
Inner 2
Inner 3
Inner 4
Outer 3
Inner 0
Inner 1
Inner 2
Inner 3
Inner 4
Outer 4
Inner 0
Inner 1
Inner 2
Inner 3
Inner 4


I was trying to understand the output.Why outer loop did not execute until 50 times( ask<51). Please advise. Any links, ideas, resources,sample code highly appreciated. thanks in advance.
