title: Java JFrame Size according to screen resolution
body: <p>I created java GUI using myEclipse Matisse. when my Screen Resolution is 1024x768 it works fine but when i change resolution my GUI is not working fine. I want my GUI window should be re-sized according to the screen Resolution
  I am extending JFrame to create the main window. </p>
  
  <pre class="lang-java prettyprint-override"><code>public class MyClass extends JFrame {
  
      //I am putting some controls here.
  
      Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
      setBounds(0,0,screenSize.width, screenSize.height);
      setVisible(true);
  
      pack();
  }
  </code></pre>
  
  <p>this is not working, what ever i do, setting size hardcoded or by ToolKit using, the Frame Size Remains same.</p>
