在 java 的 GUI 中，除了 .north、.south、.east、.west、.center 之外，我还能使用什么？

Question

   add(banner, BorderLayout.NORTH);
  add(bread, BorderLayout.CENTER);
  add(sandwiches, BorderLayout.EAST);
  add(drinks, BorderLayout.WEST);
  add(buttonPanel, BorderLayout.SOUTH);

I currently have a GUI and have used these 5 location allocation. Is there another one I can use if I want to add another panel on the right side?

Answer 1

I want to add another panel on the right side?

So you create another child JPanel with the appropriate layout manager:

JPanel east = new JPanel( new BorderLayout() );
east.add(sandwiches, BorderLayout.LINE_START);

JPanel anotherPanel = new JPanel( new GridLayout(0, 1) );
anotherPanel.add( new JButton("Button1") );
anotherPanel.add( new JButton("Button2") );

east.add(anotherPanel, BorderLayout.LINE_END);

//add(sandwiches, BorderLayout.EAST);
add(east, BorderLayout.EAST);

So the "east" panel becomes a nested panel that contains two other panels.
