• 框架构建
• 时间设置面板，倒计时面板

• 按钮设置

  3.本身的代码提交记录截图

4.本身负责模块或任务详细说明

1.框架构建

public TimeFrame() {
        add(new TimePanel());

        this.setTitle("定时器");
        this.setSize(1200, 800);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.setLocationRelativeTo(null);
        this.setResizable(false);
        this.setVisible(true);
    }

2.建立类

class TimePanel extends JPanel implements ActionListener, KeyListener, Runnable {

        /**
         * 
         */
        private static final long serialVersionUID = 1L;
        
        private int setTime;
        private int showTime;
        // 定义是否计时变量
        private boolean flag = false;
        private JPanel jpShowTime, jpSetting, jpTimeInfo;

        private JLabel labTime, labSetTime, labPassTime, labRemainTime;
        private JButton btnBegin;
        private JButton btnPause;
        private JButton btnContinue;
        private JButton btnHidden;
        private JButton btnShow;
        private JButton btnExit;
        // 倒计时设置
        private JPanel jpTimeSetting;
        private JTextField tfdHours;
        private JTextField tfdMinutes;
        private JTextField tfdSeconds;

        public TimePanel() {
            this.setSize(1200, 800);
            this.setLayout(null);

            createSetting();
            createShowTime();
            
            jpSetting.addKeyListener(this);
            jpSetting.setFocusable(true);
        }

3.建立倒计时面板、设置时间面板、倒计时属性面板、时间信息面板

void createShowTime() {
            jpShowTime = new JPanel();
            jpShowTime.setSize(1200, 400);
            jpShowTime.setBackground(Color.BLACK);

            labTime = new JLabel("00 : 00 : 00", JLabel.CENTER);
            labTime.setFont(new Font("微软雅黑", 1, 200));
            labTime.setForeground(Color.RED);
            jpShowTime.add(labTime);

            add(jpShowTime).setBounds(0, 400, 1200, 400);

        }
void createSetting() {
            jpSetting = new JPanel();
            jpSetting.setSize(1200, 400);
            jpSetting.setLayout(null);

            createTimeSetting();
            createTimeInfo();

            // 开始按钮
            btnBegin = new JButton("开始[F8]");
            jpSetting.add(btnBegin).setBounds(700, 50, 80, 50);
            // 暂停按钮
            btnPause = new JButton("暂停[F9]");
            jpSetting.add(btnPause).setBounds(800, 50, 80, 50);
            // 继续按钮
            btnContinue = new JButton("继续[F10]");
            jpSetting.add(btnContinue).setBounds(900, 50, 80, 50);
            // 隐藏按钮
            btnHidden = new JButton("隐藏[F11]");
            jpSetting.add(btnHidden).setBounds(700, 120, 80, 50);
            // 显示按钮
            btnShow = new JButton("显示[F12]");
            jpSetting.add(btnShow).setBounds(800, 120, 80, 50);
            // 帮助按钮
            btnExit = new JButton("退出");
            jpSetting.add(btnExit).setBounds(900, 120, 80, 50);

            btnBegin.addActionListener(this);
            btnPause.addActionListener(this);
            btnContinue.addActionListener(this);
            btnHidden.addActionListener(this);
            btnShow.addActionListener(this);
            btnExit.addActionListener(this);

            add(jpSetting).setBounds(0, 0, 1200, 400);
        }
void createTimeSetting() {
            jpTimeSetting = new JPanel();
            jpTimeSetting.setSize(300, 200);
            jpTimeSetting.setLayout(new FlowLayout());

            jpTimeSetting.add(tfdHours = new JTextField(3));
            jpTimeSetting.add(new JLabel("时"));
            jpTimeSetting.add(tfdMinutes = new JTextField(3));
            jpTimeSetting.add(new JLabel("分"));
            jpTimeSetting.add(tfdSeconds = new JTextField(3));
            jpTimeSetting.add(new JLabel("秒"));
            
            tfdHours.addKeyListener(this);
            tfdMinutes.addKeyListener(this);
            tfdSeconds.addKeyListener(this);

            jpSetting.add(jpTimeSetting).setBounds(100, 100, 300, 200);
        }
void createTimeInfo() {
            jpTimeInfo = new JPanel();
            jpTimeInfo.setLayout(null);
            jpTimeInfo.setBackground(new Color(154, 217, 250));
            jpTimeInfo.setSize(1200, 100);
            // 总秒数
            labSetTime = new JLabel("计时总秒数 : ", JLabel.CENTER);
            labSetTime.setFont(new Font("微软雅黑", 0, 20));
            jpTimeInfo.add(labSetTime).setBounds(0, 10, 400, 80);
            // 已过秒数
            labPassTime = new JLabel("已过秒数 : ", JLabel.CENTER);
            labPassTime.setFont(new Font("微软雅黑", 0, 20));
            jpTimeInfo.add(labPassTime).setBounds(400, 10, 400, 80);
            // 剩余秒数
            labRemainTime = new JLabel("剩余秒数 : ", JLabel.CENTER);
            labRemainTime.setFont(new Font("微软雅黑", 0, 20));
            jpTimeInfo.add(labRemainTime).setBounds(800, 10, 400, 80);

            jpSetting.add(jpTimeInfo).setBounds(0, 300, 1200, 100);
        }

5.课程设计感想

虽然时间紧迫，可是作了组长仍是要负责好课设，因而和组员一直讨论要怎么搞才好，沟通交流是作课设最主要的，分配好各自的工做而后讨论交流才让咱们的课设最终完成。最后的最后，不懂的~要百度~
