Question

Just a quick question here. I have a program in which I need to create a number of JPanels, which will then each contain some objects (usually JLabels).

There are a few operations that I have to do each time i create a new JPanel, and I’m wondering if the order in which I do them has any bearing, or if there is a standard practice.

The operations I do are the following:

Declare the JPanel: JPanel panel = new JPanel(…)

Declare the JLabel: JLabel laberl = new JLabel…

Add the JPanel to some other content pane: frame.getContentPane().add(panel)

Set the bounds of the JPanel: panel.setBounds(…)

Add the JLabel to the JPanel: panel.add(label)

Answer 1

Have a method createPanel() that returns the panel with all its children added.

Panel p = createPanel();
p.setBounds(...); // if you must
frame.getContentPane().add(p);

And then

Panel createPanel() {
  Panel p = new Panel();
  Label l = new Label("Heading");
  p.add(l);
  return p;
}

The order of constructing and adding items isn’t important, except that when you add children, you should add them in the order you want them in the panel.
