title: JFrame not sizing correctly
body: <p>When I set the size of the JFrame its set the size of the frame itself including the borders.
  I tried creating a new content Panel and set that size instead of setting the size of the frame itself but it isn't working here is the code:</p>
  
  <pre><code>frame = new JFrame();
  JPanel jp = new JPanel();
  frame.setTitle(title);
  //frame.setSize(width, height);
  frame.setResizable(false); 
  frame.setLocationRelativeTo(null);
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  //insets = frame.getInsets();
  //frame.setSize(new Dimension(insets.left + width + insets.right, insets.top + height + insets.bottom));
  jp.setPreferredSize(new Dimension(width, height));
  frame.setContentPane(jp);
  frame.pack();
  frame.setVisible(true);
  </code></pre>
  
  <p>So using insets isn't working and using a new ContentPane is also not working I hope it is clear enough.</p>
  
  <p><strong>EDIT:</strong> It's working now I extended the class with Canvas set it's size to width and height and then added it to the JFrame then packed it. This works! But why I think caused it was not the sizing but the way I rendered it, I got the bufferStrategy from the JFrame instead of the canvas which is not the way it should be.</p>
