Java写的自动关机软件.docx

效果图：/* * 想法： * 1.用户单击设定关机时间，就弹出一个对话框，要求设定关机时间。 * 2.当用户未设定关机时间时，关机时间默认为（未设定），关机剩余时间为（未了解），而当 * 用户单击并确定了关机时间时，在主界面立即显示关机时间和关机剩余时间（不停变化）。 * 3.此处不用真正的关机，而是用（打开记事本）来代替关机，后期调试无误之后再用真正的关机替代回来。 * 4.应该为字体的颜色和字体格式分别建立一个类 * 设定字体的颜色：Font font=new Font(楷体,Font.PLAIN,16);jLabel.setFont(font); * 5.当前时间和设定的关机时间相等时，应弹出一个对话框，默认存在10秒，问：是否关机？（答：是 或 否） * 如果10秒内没有操作，则执行关机。 */package com.view;import javax.swing.*;import javax.swing.Timer;import javax.swing.text.Position.Bias;import java.text.SimpleDateFormat;import java.util.*;import java.awt.*;import java.awt.event.*;import java.io.*;import javax.imageio.*;public class ShutDownViewpublic static String myTime;public static void main(String args)ShowCurrentTime showCurrentTime=new ShowCurrentTime();Thread thread1=new Thread(showCurrentTime);thread1.start();class ShowCurrentTime extends JFrame implements Runnable,ActionListenerSimpleDateFormat timeFormat;JLabel jLabel,timeNow,timeShow1,timeShut,timeShow2;JButton jButton1,jButton2;int width,height;/构造函数public ShowCurrentTime()/设置时间的格式timeFormat=new SimpleDateFormat(HH:mm:ss);/手型光标Cursor myCursor=new Cursor(Cursor.HAND_CURSOR);/timer =new Timer(1000, this);/timer.start();jLabel=new JLabel(距离关机剩余：);jLabel.setBounds(0,0,100, 20);this.add(jLabel);timeShow1=new JLabel(当前时间：);timeShow1.setBounds(160, 40, 120, 30);this.add(timeShow1);timeNow=new JLabel();timeNow.setBounds(160, 60, 120, 30);this.add(timeNow);jButton1=new JButton(new ImageIcon(images/time.gif);jButton1.setCursor(myCursor);jButton1.setBounds(160, 0, 120, 30);jButton1.addActionListener(this);this.add(jButton1);jButton2=new JButton(new ImageIcon(images/now.gif);jButton2.setCursor(myCursor);jButton2.setBounds(115, 125,45, 35);this.add(jButton2);/关机时间timeShow2 =new JLabel(关机时间：);timeShow2.setBounds(0, 40, 100,30 );this.add(timeShow2);timeShut=new JLabel(尚未设定时间);timeShut.setBounds(0, 60, 100,30 );this.add(timeShut);/得到屏幕的宽和高width =Toolkit.getDefaultToolkit().getScreenSize().width;height =Toolkit.getDefaultToolkit().getScreenSize().height;this.setLayout(null);BackImage backImage=new BackImage();/确定图片位置backImage.setBounds(0,0,280,280);this.add(backImage);this.setLocation(width-280)/2, (height-280)/2);this.setSize(283,305);this.setVisible(true);this.setResizable(false);this.setDefaultCloseOperation(EXIT_ON_CLOSE);addWindowListener(new WindowAdapter() public void windowClosing(WindowEvent e) int n=JOptionPane.showConfirmDialog(null,确认退出吗?,确认对话框,JOptionPane.YES_NO_OPTION );
