UIManager被我封装在类里面了
package Cffx;import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class MyLookAndFeel {

public static void setLookAndFeel(String skin){
try {
UIManager.setLookAndFeel(skin);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (InstantiationException e) {
