java编程闹钟1.doc

编写时钟程序，要求画出时钟面板，时针，分针，秒针，可设定或解除闹钟时间，并提供闹钟服务相应的文字提示功能与声音提示功能。最佳答案 自己之前做过的一个：import java.awt.*;import java.awt.event.*;import java.util.*;import javax.swing.*;import javax.swing.Timer;public class Clock extends JFrame implements ActionListener public final int HEIGTH = 200, L0 = 50, T0 = 50,N=8;
