一、程序基本要求如下
- 自动生成题目,单个题目最多不能超过4个运算符,操作数小于100。
- 用户可以输入答案
- 若用户输入答案正确,则提示正确;若答案错误,则提示错误,并要提示正确答案是多少。
二、扩展方向(8选4)
1.程序可以出带括号的正整数四则运算,支持分数,除法保留两位小数
2.用户答题结束以后,程序可以显示用户答题所用的时间
3.答题结束可以显示用户答错的题目个数和答对的题目个数
4.用户在第一次答题时,需要用户输入用户名,用户下次启动后,程序需要记住用户前一次输入的用户名

五、部分代码:
小程序界面代码:
public Main() { //创建组件 jb1=new JButton("确认"); jb1.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent arg0) { String N=Name.getText(); String M=Number.getText(); name.add(N); number.add(M); Start frame = new Start(); frame.setTitle("四则运算训练小程序"); frame.setSize(600,400); frame.setLocationRelativeTo(null); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); frame.setVisible(true); // 打开新界面 dispose(); // 关闭当前界面 try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (Exception e) { e.printStackTrace(); } 统计分数代码: int size = list1.size(); int errorSum = size - rightSum; JFrame resultFrame = new JFrame(); resultFrame.setTitle("运算结果"); resultFrame.setSize(500, 500); resultFrame.setLocationRelativeTo(null); resultFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); resultFrame.setVisible(true); JPanel panel7 = new JPanel(); Timelabel.setText("答题用时为:" + time +" "+"做题总数: " + size + " " + "正确数:" + rightSum + " " + " 最终得分:" + rightSum * 5); panel7.add(Timelabel); resultFrame.add(panel7, BorderLayout.NORTH); JPanel panel = new JPanel(); Font font = new Font(Font.DIALOG, Font.PLAIN, 20); JTable table = new JTable(); String[] columns = { " 题 目 ", " 你的答案 "," 正确答案 "," 状 态 " }; int[] columnWidth={160,120,120,50}; DefaultTableModel model = new DefaultTableModel(columns, 0); table.setModel(model); JScrollPane scrollPane = new JScrollPane(table); //支持滚动 TableColumnModel columnModel=table.getColumnModel(); int count=columnModel.getColumnCount(); javax.swing.table.TableColumn column =columnModel.getColumn(0); column.setPreferredWidth(columnWidth[0]); 计算做题时间代码: public class Timer extends JFrame { private static final long serialVersionUID = 1L; private static final String INITIAL_LABEL_TEXT = "00:00:00 000"; // 计数线程 private CountingThread thread = new CountingThread(); // 记录程序开始时间 private long programStart = System.currentTimeMillis(); // 程序一开始就是暂停的 private long pauseStart = programStart; // 程序暂停的总时间 private long pauseCount = 0; private JLabel label = new JLabel(INITIAL_LABEL_TEXT); private JButton startPauseButton = new JButton("开始"); private JButton resetButton = new JButton("清零"); String time; private ActionListener startPauseButtonListener = new ActionListener() { public void actionPerformed(ActionEvent e) { if (thread.stopped) { pauseCount += (System.currentTimeMillis() - pauseStart); thread.stopped = false; startPauseButton.setText("暂停"); } else { pauseStart = System.currentTimeMillis(); thread.stopped = true;
ton("确认"); jb1.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent arg0) { String N=Name.getText(); String M=Number.getText(); name.add(N); number.add(M); Start frame = new Start(); frame.setTitle("四则运算训练小程序"); frame.setSize(600,400); frame.setLocationRelativeTo(null); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); frame.setVisible(true); // 打开新界面 dispose(); // 关闭当前界面 try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (Exception e) { e.printStackTrace(); } 统计分数代码: int size = list1.size(); int errorSum = size - rightSum; JFrame resultFrame = new JFrame(); resultFrame.setTitle("运算结果"); resultFrame.setSize(500, 500); resultFrame.setLocationRelativeTo(null); resultFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); resultFrame.setVisible(true); JPanel panel7 = new JPanel(); Timelabel.setText("答题用时为:" + time +" "+"做题总数: " + size + " " + "正确数:" + rightSum + " " + " 最终得分:" + rightSum * 5); panel7.add(Timelabel); resultFrame.add(panel7, BorderLayout.NORTH); JPanel panel = new JPanel(); Font font = new Font(Font.DIALOG, Font.PLAIN, 20); JTable table = new JTable(); String[] columns = { " 题 目 ", " 你的答案 "," 正确答案 "," 状 态 " }; int[] columnWidth={160,120,120,50}; DefaultTableModel model = new DefaultTableModel(columns, 0); table.setModel(model); JScrollPane scrollPane = new JScrollPane(table); //支持滚动 TableColumnModel columnModel=table.getColumnModel(); int count=columnModel.getColumnCount(); javax.swing.table.TableColumn column =columnModel.getColumn(0); column.setPreferredWidth(columnWidth[0]); 计算做题时间代码: public class Timer extends JFrame { private static final long serialVersionUID = 1L; private static final String INITIAL_LABEL_TEXT = "00:00:00 000"; // 计数线程 private CountingThread thread = new CountingThread(); // 记录程序开始时间 private long programStart = System.currentTimeMillis(); // 程序一开始就是暂停的 private long pauseStart = programStart; // 程序暂停的总时间 private long pauseCount = 0; private JLabel label = new JLabel(INITIAL_LABEL_TEXT); private JButton startPauseButton = new JButton("开始"); private JButton resetButton = new JButton("清零"); String time; private ActionListener startPauseButtonListener = new ActionListener() { public void actionPerformed(ActionEvent e) { if (thread.stopped) { pauseCount += (System.currentTimeMillis() - pauseStart); thread.stopped = false; startPauseButton.setText("暂停"); } else { pauseStart = System.currentTimeMillis(); thread.stopped = true;

七、总结感悟
做这个项目综合了很多以前学的知识,让我对旧知识进行了一些回顾学习,收获颇多。
