title: Eclipse Display Window doesn't work I can't run anything there
body: <p>Eclipse Display Window doesn't work I can't run anything there.</p>
  
  <p>For example I am trying to do this in the Display view window:</p>
  
  <pre><code>  System.out.println("test")
  </code></pre>
  
  <p>But nothing happens, and when I looked in Eclipse documentationa and in the internet I found that the j icon on the upper right corner of the Display window should be active after I highlight the line of code or I can right click after I highlight the code and see the option to execute the code. but nothing is working. </p>
  
  <p>Please help. </p>
