title: how many times is the println statement executed
body: <p>I kind of don't get the nested loops, can someone explain to me why the following code is executed 45 times please? Shouldn't the i++ and j++ increment by 1? So first loop should be (0 * 0), (1 * 1), (2 * 2) and so on.</p>
  
  <pre><code>for(int i = 0; i &lt; 10; i++)
      for(int j = 0; j &lt; i; j++)
          System.out.println(i * j);
  </code></pre>
