why aren't my JLabels and JTextFields showing up in the JPanel?

I have a JDialog and inside it I have a JPanel that uses FlowLayout

now I've created 3 labels and text fields using the Netbeans GUI Builder, and I want to add 2 more text fields using code

I've adjusted the size of the panel so that when I add a new label and a textfield with a preferred size the new set of label - textfield will be under the previous set

somewhere in the JDialog I do something like this

        JLabel cores = new JLabel("Cores");
        cores.setPreferredSize(new Dimension(70,15));
        first = new JTextField();
        first.setPreferredSize(new Dimension(140,20));
        JLabel power = new JLabel("Power");
        power.setPreferredSize(new Dimension(70,15));
        second = new JTextField();
        second.setPreferredSize(new Dimension(140,20));
        panel2.add(cores);panel2.add(first);panel2.add(power);panel2.add(second);

when I compile the program, the labels don't show up and neither do the textfields

when I go down and click I have the following result

if I type something, the text field appears

the labels don't appear though, I don't think I made any changes to the properties, any help would be appreciated thanks

Solution

  • Define the no of columns while creating object.
    like this 

    JTextField jt=new JTextField(20);
