Hi everyone, I'm having trouble with this code. It compiles fine, but clicking the menu item I just added the actionlistener to doesn't work. I'm new to java and I can't figure it out.

You want to add that action listener to jMenuItem1 instead of jMenu1. Also, you aren't showing the dialog. I would recommend using the static JOptionPane method to show the dialog

JOptionPane.showMessageDialog(NewJFrame.this, "You pressed New.");
