    text
    copied!<p>I am new to Swing and was making a very basic event handling program in Eclipse. Here is the code that i wrote:</p> <pre><code>public class SwingDemo2 { JLabel jl; public SwingDemo2() { JFrame jfr = new JFrame("Swing Event Handling"); jfr.setSize(250, 100); jfr.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); jl = new JLabel(); jl.setVisible(false); JButton jb1 = new JButton("OK"); jb1.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent ae) { jl.setText("You Pressed OK"); jl.setVisible(true); } }); JButton jb2 = new JButton("Reset"); jb2.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent ae) { jl.setText("You Pressed Reset"); jl.setVisible(true); } }); jfr.setLayout(new BorderLayout()); jfr.add(jl, SwingConstants.NORTH); jfr.add(jb1, SwingConstants.EAST); jfr.add(jb2, SwingConstants.WEST); jfr.setVisible(true); } public static void main(String[] args) { // TODO Auto-generated method stub SwingUtilities.invokeLater(new Runnable() { public void run() { new SwingDemo2(); } }); } } </code></pre> <p>Eclipse prompts me to open the debug perspective where he shows me the error:<br> <code>Thread [AWT-EventQueue-0] (Suspended (exception IllegalArgumentException))</code> <code>EventDispatchThread.run() line: not available [local variables unavailable]</code></p> <p>I didn't get any error when I used <code>FlowLayout</code> instead of <code>BorderLayout</code>.</p> <p>I have been trying to find info on the error on the portal, i came across <a href="https://stackoverflow.com/questions/5080912/java-error-eventdispatchthread-run-line-not-available-local-variables-unava">this</a> similar question. The answer is to change a bunch of settings (which didn't help either) without explaining the problem. Please explain the error so that i can make sure not to repeat it. Thanx in advance!</p> <p>Note: Updated the error message</p>
