title: Counting in Java - Text field shows only last value
body: <p>I've got a problem with my simulation of processor counter in java. I want to counting for example from 0 to 6 and show current values of counting (0, 1, 2, 3, 4, 5, 6) in Text field. When I click "Count" button, my program freezes for a moment and after counting in Text field I can see only number 6. I want to see other numbers during the counting. Here is part of my code:</p>
  
  <pre><code>for (int b=0; b&lt;30; b++)
          {
             counter2.Count();
             try {
                      Thread.sleep(300);
                  } catch(InterruptedException e){}
             text6.setText("TEST" + counter2.MainReg); }
  </code></pre>
  
  <p>What can I do with it?
  Thank you for helping me.</p>
