Java课程设计-定时器

4.自己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.创建类

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.创建倒计时面板、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,但是做了组长还是要负责好课设,于是和组员一直讨论要怎么搞才好,沟通交流是做课设最主要的,分配好各自的工作然后讨论交流才让我们的课设最终完成。最后的最后,不懂的~要百度~
