Align JLabel to left or right on JPanel

Question

如何将JPanel的黄色JLabel向右移动/对齐，并将其他JLabel向左移动/对齐？

Answer 1

You use an appropriate layout manager.

One option is to use a panel with a horizontal BoxLayout :

Box panel = Box.createHorizontalBox();
panel.add( leftLabel );
panel.add( Box.createHorizontalGlue() );
panel.add( yellowLabel );

Another option is to use a panel with a BorderLayout :

JPanel panel = new JPanel( new BorderLayout() );
panel.add(leftLabel, BorderLayout.LINE_START);
panel.add(yellowLabel, BorderLayout.LINE_END);

Read the section from the Swing tutorial on Layout Mangers for more information and working examples.
