title: Can this code be more efficient?
body: <p>This Program should do this</p>
  
  <pre><code>N 10*N 100*N 1000*N
  1 10  100    1000
  2 20  200    2000
  3 30  300    3000
  4 40 400     4000
  5 50 500    5000
  </code></pre>
  
  <p>So here's my code:</p>
  
  <pre><code>public class ex_4_21 {
  
      public static void main( String Args[] ){
  
      int process = 1;
      int process2 = 1;
      int process22 = 1;
      int process3 = 1;
      int process33 = 2;
  
      System.out.println("N   10*N   100*N   1000*N");
      while(process&lt;=5){
  
          while(process2&lt;=3){
          System.out.printf("%d   ",process2);
  
          while(process22&lt;=3){
              process2 = process2 * 10;
              System.out.printf("%d     ",process2);
              process22++;
          }
          process2++;
          }
  
  
          process++;
      }
  
      }
  }   
  </code></pre>
  
  <p>Can my code be more effecient? I am currently learning while loops.  So far this what I got. Can anyone make this more efficient, or give me ideas on how to make my code more efficient?</p>
  
  <p>This is not a homework, i am self studying java</p>
