If there is no need to resize them, you can simply use a BorderLayoutand insert your panels in the BorderLayout.EASTand BorderLayout.WEST:
如果不需要调整它们的大小，您可以简单地使用 aBorderLayout并将面板插入BorderLayout.EAST和BorderLayout.WEST：
JPanel panel = new JPanel( new BorderLayout() );
panel.add( leftPanel, BorderLayout.WEST );
panel.add( rightPanel, BorderLayout.EAST );
You could also consider using a JSplitPanewhich allows to resize the UI:
您还可以考虑使用JSplitPane允许调整 UI 大小的 a：
JSplitPane pane = new JSplitPane( JSplitPane.HORIZONTAL_SPLIT,
leftPanel, rightPanel );

使用JSplitPane或 GridLayout
回答by Kishor Prakash
You can use SplitPane as Costis Aivalis suggested.
Or
Use Border Layout Manageron JPanel.
Put your left side components in WEST side and put your right side components in EAST side of layout manager.
您可以按照 Costis Aivalis 的建议使用 SplitPane。
或者在 JPanel 上
使用边框布局管理器。
将左侧组件放在 WEST 侧，将右侧组件放在布局管理器的 EAST 侧。
JPanel panel = new JPanel(new BorderLayout());
panel.add(c1, BorderLayout.WEST);
panel.add(c2, BorderLayout.EAST);
