如何使用边框布局？

Question

I'm currently working on Layouts in Java. I'm trying to combine different layouts. So i have created a login Screen using Spring Layout, GridLayout and Border Layout. The MainFrame (JFrame) uses GridLayout. The GridLayout consists of 2 Panel (North Panel and Main Panel). The Main Panel consists of the Jlabel, JTextfield and JButton of which I have no problem of. My problem is in the North Panel which uses Border Layout. It contains a JLabel (lblWelcome). I have been trying to bring the label to the center of the panel using Border Layout but it still aligns to the left. This is the below code:

  JLabel lblWelcome = new JLabel("Welcome To The Login Screen");
  JPanel northPanel = new JPanel(new BorderLayout());
  northPanel.setBackground(Color.green);
  northPanel.add(lblWelcome, BorderLayout.CENTER);

Answer 1

Your JLabel is actually correctly centered, but its text isn't.

Simply change its creation to :

JLabel lblWelcome = new JLabel("Welcome To The Login Screen", SwingConstants.CENTER);
