第二步：设置面板属性
package time;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Font;
import java.awt.Image;
import java.awt.Toolkit;
import java.net.URL;
import javax.swing.JFrame;
import javax.swing.UIManager;

IDE:Eclipse
class:JTextFieldFrameClass 设置面板属性
*/
class JTextFieldFrameClass extends JFrame {
/**
*
*/
private static final long serialVersionUID = 1L;
ClockPanelClass clock;
public JTextFieldFrameClass(){
super("时钟");
setSize(240,370);
clock=new ClockPanelClass();
//设置clock在面板的中间显示
getContentPane().add(clock,BorderLayout.CENTER);
this.setColor.RED);
//设置居中显示
this.setLocationRelativeTo(null);
//修改java左上角的图标
URL url = this.getClass().getResource("clock.png");
Image img = Toolkit.getDefaultToolkit().getImage(url);
this.setIconImage(img);
//设置面板可见
setVisible(true);
//设置不可变大
setResizable(false);
}
}
第三步：main主函数调用写好的方法
package time;
import javax.swing.JFrame;
/**

class:Test2 main主函数
*/
class ColockMain {
public static void main(String []args){
JTextFieldFrameClass frame=new JTextFieldFrameClass();
Thread tt=new Thread(frame.clock);
tt.start();
//关闭窗口，退出应用！
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
