    Default My frame wont show anything

    My components dont show until I resize the frame.

    public class Frame extends JFrame{
     
    	private final static int WIDTH=400, HEIGHT=400;
     
        public Frame(){
            super();
            super.setSize(WIDTH,HEIGHT);
    		super.setVisible(true);
            super.setDefaultCloseOperation(EXIT_ON_CLOSE);
        }
     
    }

    	public class Panel extends JPanel{
     
    		private JTextField name;
     
     
     
    	    public Panel(){
    	    	super.setLayout(new BorderLayout());
    	        DrinkName = new JTextField(20);
    	        this.add(DrinkName, BorderLayout.SOUTH);
     
     
    	    }
     
    	}
    In my main class I am just creating the frame and the panel then adding the panel to the frame.

    Do you have a main() method for execution? Please post it.

    BTW It's best not to give your classes the same name as a Java SE class: Frame and Panel. Add a prefix like My to make them yours.
    If you don't understand my answer, don't ignore it, ask a question.

    Please refer to a basic Swing tutorial, like this one. There's also this index to choose from when you're ready to move to the next topic.

    I figured out that the problem was in my main. I rearranged the way I created the panel and frame and then put the panel in the frame. It is working now.

    One more question... Which class is recommended for button listeners? Are they allowed to go in the main?
