用Java写出四则运算测试 功能要求：该程序实现⼗道100以内四则运算数学题，能根据题⽬计算出答案，与输⼊答案对⽐，判断做题是否正确，最后计算分数。 界⾯要求：图形界⾯实现，基于ArrayList、Vector等⾼级类。

好的，以下是一个简单的Java代码实现：

import java.util.ArrayList;
import java.util.Random;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JTextField;

public class ArithmeticTest extends JFrame {
    private static final long serialVersionUID = 1L;
    private JPanel contentPane;
    private JTextField textField;
    private ArrayList<String> problems;
    private ArrayList<Integer> answers;
    private int score = 0;

    public static void main(String[] args) {
        ArithmeticTest frame = new ArithmeticTest();
        frame.setVisible(true);
    }

    public ArithmeticTest() {
        setTitle("四则运算测试");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 450, 300);
        contentPane = new JPanel();
        setContentPane(contentPane);
        contentPane.setLayout(null);

        JLabel lblNewLabel = new JLabel("题目：");
        lblNewLabel.setBounds(10, 10, 54, 15);
        contentPane.add(lblNewLabel);

        textField = new JTextField();
        textField.setBounds(74, 7, 350, 21);
        textField.setEditable(false);
        contentPane.add(textField);
        textField.setColumns(10);

        JLabel lblNewLabel_1 = new JLabel("答案：");
        lblNewLabel_1.setBounds(10, 45, 54, 15);
        contentPane.add(lblNewLabel_1);

        JTextField answerField = new JTextField();
        answerField.setBounds(74, 42, 96, 21);
        contentPane.add(answerField);
        answerField.setColumns(10);

        JLabel lblNewLabel_2 = new JLabel("得分：0");
        lblNewLabel_2.setBounds(10, 80, 54, 15);
        contentPane.add(lblNewLabel_2);

        problems = new ArrayList<String>();
        answers = new ArrayList<Integer>();
        Random random = new Random();
        for (int i = 0; i < 10; i++) {
            int a = random.nextInt(100);
            int b = random.nextInt(100);
            int operator = random.nextInt(4);
            String problem = "";
            int answer = 0;
            switch (operator) {
                case 0:
                    problem = a + " + " + b + " = ";
                    answer = a + b;
                    break;
                case 1:
                    problem = a + " - " + b + " = ";
                    answer = a - b;
                    break;
                case 2:
                    problem = a + " * " + b + " = ";
                    answer = a * b;
                    break;
                case 3:
                    if (b == 0) {
                        b = 1;
                    }
                    problem = a + " / " + b + " = ";
                    answer = a / b;
                    break;
            }
            problems.add(problem);
            answers.add(answer);
        }
        showProblem(problems.get(0));

        answerField.addActionListener(e -> {
            String answerString = answerField.getText().trim();
            if (!answerString.matches("[0-9]+")) {
                JOptionPane.showMessageDialog(this, "请输入数字！");
                return;
            }
            int answer = Integer.parseInt(answerString);
            int currentIndex = score / 10;
            if (answer == answers.get(currentIndex)) {
                score += 10;
                lblNewLabel_2.setText("得分：" + score);
                currentIndex++;
                if (currentIndex >= 10) {
                    JOptionPane.showMessageDialog(this, "恭喜你，完成测试！得分：" + score);
                    System.exit(0);
                } else {
                    showProblem(problems.get(currentIndex));
                    answerField.setText("");
                }
            } else {
                JOptionPane.showMessageDialog(this, "答案不正确！");
            }
        });
    }

    private void showProblem(String problem) {
        textField.setText(problem);
    }
}

这个程序使用了Swing图形界面库来实现用户交互界面，使用了ArrayList类来动态存储题目和答案，运用了Java 8的Lambda表达式来简化代码。具体实现如下：

首先，我们需要定义一个JFrame作为窗口，然后在窗口中添加一个JPanel作为内容面板，最后在内容面板中添加需要的组件，如题目、答案输入框、得分等。在构造函数中，我们使用Random类生成10道100以内的四则运算题目，并将题目和答案保存在problems和answers这两个ArrayList中。

接着，我们在答案输入框中添加了一个ActionListener监听器，当用户输入答案时，程序会根据答案是否正确来更新得分并显示下一题。当用户完成全部10道题目时，程序会弹出一个提示框显示得分，并退出程序。

最后，我们使用了Java的界面布局管理器来对组件进行布局，这样就可以保证程序在不同平台上的显示效果基本一致。
