可以用java使用列表框、组合框和菜单组件制作一个算术运算器示例吗。要求可以输入五个数据，第一行为初始数据，下面四行为均可输入数据并可自由选择“+-*/”四个符号来参与运算，最后一行用“=”符号来运算结果。四行运算符没有优 先级，按照顺序运算。增加要求：①采用文本行数组，操作数个数为5个②解决除数为 0的问题③区分“/”为整数除或实数除

好的，下面是一个简单的Java算术运算器示例，使用了列表框、组合框和菜单组件：

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

public class ArithmeticCalculator extends JFrame implements ActionListener {
    private static final int WIDTH = 500;
    private static final int HEIGHT = 350;

    private JTextField[] inputFields = new JTextField[5];
    private JComboBox<String>[] operatorBoxes = new JComboBox[4];
    private JTextField resultField = new JTextField();
    private JButton calculateButton = new JButton("Calculate");

    public ArithmeticCalculator() {
        setTitle("Arithmetic Calculator");
        setSize(WIDTH, HEIGHT);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JPanel inputPanel = new JPanel(new GridLayout(5, 2));
        inputPanel.add(new JLabel("Input 1:"));
        inputFields[0] = new JTextField();
        inputPanel.add(inputFields[0]);
        for (int i = 1; i < 5; i++) {
            inputPanel.add(new JLabel("Input " + (i + 1) + ":"));
            inputFields[i] = new JTextField();
            inputPanel.add(inputFields[i]);
        }
        getContentPane().add(inputPanel, BorderLayout.NORTH);

        JPanel operatorPanel = new JPanel(new GridLayout(4, 2));
        for (int i = 0; i < 4; i++) {
            operatorPanel.add(new JLabel("Operator " + (i + 1) + ":"));
            operatorBoxes[i] = new JComboBox<>(new String[]{"+", "-", "*", "/", "÷"});
            operatorBoxes[i].addActionListener(this);
            operatorPanel.add(operatorBoxes[i]);
        }
        getContentPane().add(operatorPanel, BorderLayout.CENTER);

        JPanel resultPanel = new JPanel(new GridLayout(1, 2));
        resultPanel.add(new JLabel("Result:"));
        resultField.setEditable(false);
        resultPanel.add(resultField);
        getContentPane().add(resultPanel, BorderLayout.SOUTH);

        calculateButton.addActionListener(this);
        getContentPane().add(calculateButton, BorderLayout.EAST);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == calculateButton) {
            double result = Double.parseDouble(inputFields[0].getText());
            for (int i = 0; i < 4; i++) {
                String operator = (String) operatorBoxes[i].getSelectedItem();
                double operand = Double.parseDouble(inputFields[i + 1].getText());
                switch (operator) {
                    case "+":
                        result += operand;
                        break;
                    case "-":
                        result -= operand;
                        break;
                    case "*":
                        result *= operand;
                        break;
                    case "/":
                    case "÷":
                        if (operand == 0) {
                            JOptionPane.showMessageDialog(this, "Division by zero error!");
                            return;
                        }
                        result /= operand;
                        break;
                }
            }
            resultField.setText(Double.toString(result));
        }
    }

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

在这个示例中，我们使用了`JTextField`来接收用户输入的数值，使用`JComboBox`来选择运算符，使用`JButton`来触发运算操作。在运算过程中，我们使用一个`switch`语句来根据运算符进行相应的运算，需要注意除数为0的情况。

希望这个示例能够帮助你理解如何使用Java的Swing组件库来构建算术运算器。
