使用JavaSwing要求：显示5道算式，并允许用户填入结果，单击检查按钮后，显示分数。请直接给出代码

### 回答1：
在这里给出一个示例代码，这是使用 Java Swing 实现的简单算式测试程序，可以供您参考：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;

public class Quiz extends JFrame implements ActionListener {

  // 定义 5 个算式和答案
  private int[][] equations = new int[][] {
    {3, 4, 7},
    {5, 5, 10},
    {7, 8, 15},
    {9, 10, 19},
    {11, 12, 23}
  };

  // 定义 5 个文本框，用于输入结果
  private JTextField[] answers = new JTextField[5];

  public Quiz() {
    // 设置窗口标题
    setTitle("算式测试");

    // 设置布局
    setLayout(new GridLayout(6, 2));

    // 循环显示算式
    for (int i = 0; i < 5; i++) {
      // 显示算式
      add(new JLabel(equations[i][0] + " + " + equations[i][1] + " = "));
      // 创建文本框
      answers[i] = new JTextField(10);
      // 添加文本框
      add(answers[i]);
    }

    // 创建检查按钮
    JButton checkButton = new JButton("检查");
    // 添加按钮监听器
    checkButton.addActionListener(this);
    // 添加按钮
    add(checkButton);

    // 设置窗口大小
    setSize(400, 200);
    // 设置窗口可见
    setVisible(true);
  }

  public static void main(String[] args) {
    new Quiz();
  }

  @Override
  public void actionPerformed(ActionEvent e) {
    // 统计分数
    int score = 0;
    // 循环检查答案
    for (int i = 0; i < 5; i++) {
      // 获取文本框中的答案
      int answer = Integer.parseInt

        double score = (double) correctCount / 5;

        JOptionPane.showMessageDialog(this, "Your score: " + score);

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {

    }
}

使用Java的Swing编写一个简单的数学测验程序。该程序将显示5道随机生成的算式，并允许用户填入结果。用户单击检查按钮后，程序会检查用户的答案，并显示测验分数。每道算式都是由两个1到10之间的随机整数和一个随机运算符（加号、减号、乘号或除号）组成。程序使用JFrame作为GUI窗口，并使用GridLayout来排列组件。

该程序的核心是MathQuiz类，它继承自JFrame并实现了ActionListener接口。MathQuiz类包括了5个JLabel和5个JTextField来显示算式和接收用户的答案。还包括一个JButton来触发检查答案的操作。checkAnswers()方法用于检查用户的答案，并计算测验得分。

在main()方法中，我们使用SwingUtilities的invokeLater()方法来创建并显示MathQuiz对象，以保证在事件分发线程上运行GUI代码。

这个代码提供了一个简单的Math Quiz游戏框架，您可以根据自己的需要进行扩展和优化。

以下是使用Java Swing实现的代码：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class EquationGame extends JFrame implements ActionListener {
private JLabel equationLabel1, equationLabel2, equationLabel3, equationLabel4, equationLabel5;
private JTextField resultField1, resultField2, resultField3, resultField4, resultField5;
private JButton checkButton;
private JLabel scoreLabel;

public EquationGame() {
setTitle("Equation Game");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(400, 300);
setLayout(new GridLayout(7, 2));

equationLabel1 = new JLabel("2 + 3 = ");
resultField1 = new JTextField();
add(equationLabel1);
add(resultField1);

equationLabel2 = new JLabel("4 * 5 = ");
resultField2 = new JTextField();
add(equationLabel2);
add(resultField2);

equationLabel3 = new JLabel("10 / 2 = ");
resultField3 = new JTextField();
add(equationLabel3);
add(resultField3);

equationLabel4 = new JLabel("7 - 3 = ");
resultField4 = new JTextField();
add(equationLabel4);
add(resultField4);

equationLabel5 = new JLabel("8 % 4 = ");
resultField5 = new JTextField();
add(equationLabel5);
add(resultField5);

checkButton = new JButton("检查");
checkButton.addActionListener(this);
add(checkButton);

scoreLabel = new JLabel("");
add(scoreLabel);

setVisible(true);
}

@Override
public void actionPerformed(ActionEvent e) {
if (e.getSource() == checkButton) {
int score = 0;

if (resultField1.getText().equals("5")) {
score++;
}
if (resultField2.getText().equals("20")) {
score++;
}
if (resultField3.getText().equals("5")) {
score++;
}
if (resultField4.getText().equals("4")) {
score++;
}
if (resultField5.getText().equals("0")) {
score++;
}

scoreLabel.setText("得分: " + score + "/5");
}
}

public static void main(String[] args) {
new EquationGame();
}
}

这个程序创建了一个带有5个算式和答案输入框的窗口。用户可以填写各个算式的答案，并单击检查按钮后，会根据用户的答案显示得分。
