title: Why is my JFrame image not changing the icon?
body: <p>I am trying to change the image icon on a JFrame and it is not showing up. I have tried both the absolute path to my desktop and then the path that I have in Eclipse. Why is this not working. I have looked on stackoverflow and this is how it looks like that it is probably done, but for some reason the code below is not working.</p>
  
  <p>code:</p>
  
  <pre><code>package TestMenu;
  
  import java.awt.EventQueue;
  
  import javax.swing.ImageIcon;
  import javax.swing.JFrame;
  import javax.swing.JPanel;
  import javax.swing.border.EmptyBorder;
  
  public class TestJFrame extends JFrame {
      private static final long serialVersionUID = 1L;
      private JPanel contentPane;
  
      public TestJFrame() {
          ImageIcon img = new ImageIcon("C:\\Users\\itpr13266\\workspace\\TestMenu\\src\\TestMenu\\img\\s.jpg");
          setIconImage(img.getImage());
  
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          setBounds(100, 100, 450, 300);
          contentPane = new JPanel();
          contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
          setContentPane(contentPane);
          contentPane.setLayout(null);
  
          JPanel panel = new JPanel();
          panel.setBounds(117, 105, 10, 10);
          contentPane.add(panel);
      }
  
      public static void main(String[] args) {
          EventQueue.invokeLater(new Runnable() {
              public void run() {
                  try {
                      TestJFrame frame = new TestJFrame();
                      frame.setVisible(true);
                  } catch (Exception e) {
                      e.printStackTrace();
                  }
              }
          });
      }
  }

  <p>The code is fix now. I had the wrong image format type.</p>
