Java课程设计--定时器
1.团队课程设计博客链接
2.个人负责模块或任务说明
- 框架构建
- 时间设置面板，倒计时面板
- 按钮设置
3.自己的代码提交记录截图
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~
