1、Metal風(fēng)格 (默認(rèn))
String lookAndFeel = "javax.swing.plaf.metal.MetalLookAndFeel";
UIManager.setLookAndFeel(lookAndFeel);
2、Windows風(fēng)格
String lookAndFeel = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
UIManager.setLookAndFeel(lookAndFeel);
3、Windows Classic風(fēng)格
String lookAndFeel = "com.sun.java.swing.plaf.windows.WindowsClassicLookAndFeel";
UIManager.setLookAndFeel(lookAndFeel);
4、Motif風(fēng)格
String lookAndFeel = "com.sun.java.swing.plaf.motif.MotifLookAndFeel";
UIManager.setLookAndFeel(lookAndFeel);
5、Mac風(fēng)格 (需要在相關(guān)的操作系統(tǒng)上方可實(shí)現(xiàn))
String lookAndFeel = "com.sun.java.swing.plaf.mac.MacLookAndFeel";
UIManager.setLookAndFeel(lookAndFeel);
6、GTK風(fēng)格 (需要在相關(guān)的操作系統(tǒng)上方可實(shí)現(xiàn))
String lookAndFeel = "com.sun.java.swing.plaf.gtk.GTKLookAndFeel";
UIManager.setLookAndFeel(lookAndFeel);
7、可跨平臺(tái)的默認(rèn)風(fēng)格
String lookAndFeel = UIManager.getCrossPlatformLookAndFeelClassName();
UIManager.setLookAndFeel(lookAndFeel);
8、當(dāng)前系統(tǒng)的風(fēng)格

在Java中讓用戶能夠動(dòng)態(tài)地更改應(yīng)用的外觀，可以給用戶更好地體驗(yàn)，具體的實(shí)現(xiàn)方式是：
1，先使用UIManager.setLookAndFeel(String s)方法設(shè)定對(duì)應(yīng)的外觀
2，再使用SwingUtilities.updateComponentTreeUI(Component c)方法立刻更新應(yīng)用的外觀
這兩個(gè)類均在javax.swing包中
