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~
