Answer 1

您是否希望设置"外观和感觉"？

这是链接中的代码:

// Get the native look and feel class name
String nativeLF = UIManager.getSystemLookAndFeelClassName();

// Install the look and feel
try {
 UIManager.setLookAndFeel(nativeLF);
} catch (InstantiationException e) {
} catch (ClassNotFoundException e) {
} catch (UnsupportedLookAndFeelException e) {
} catch (IllegalAccessException e) {
}
