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在数据左边可自由选择“+-*/”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

可以使用Java的Swing库来创建一个基于列表框、组合框和菜单组件的算术运算器示例。以下是一个简单的实现：

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

public class ArithmeticCalculator extends JFrame implements ActionListener {
    private JTextField[] operandFields;
    private JComboBox<String>[] operatorBoxes;
    private JTextField resultField;
    private JButton calculateButton;
    private JRadioButton intDivRadio, realDivRadio;

    public ArithmeticCalculator() {
        super("Arithmetic Calculator");

        // Create operand text fields
        operandFields = new JTextField[5];
        for (int i = 0; i < operandFields.length; i++) {
            operandFields[i] = new JTextField(5);
        }

        // Create operator combo boxes
        operatorBoxes = new JComboBox[4];
        String[] operators = {"+", "-", "*", "/"};
        for (int i = 0; i < operatorBoxes.length; i++) {
            operatorBoxes[i] = new JComboBox<String>(operators);
        }

        // Create result text field and calculate button
        resultField = new JTextField(10);
        resultField.setEditable(false);
        calculateButton = new JButton("Calculate");
        calculateButton.addActionListener(this);

        // Create radio buttons for integer or real division
        intDivRadio = new JRadioButton("Integer Division");
        realDivRadio = new JRadioButton("Real Division");
        ButtonGroup divGroup = new ButtonGroup();
        divGroup.add(intDivRadio);
        divGroup.add(realDivRadio);
        intDivRadio.setSelected(true);

        // Create panel for input fields
        JPanel inputPanel = new JPanel(new GridLayout(5, 3));
        for (int i = 0; i < 4; i++) {
            inputPanel.add(operandFields[i]);
            inputPanel.add(operatorBoxes[i]);
        }
        inputPanel.add(operandFields[4]);
        inputPanel.add(new JLabel("="));
        inputPanel.add(resultField);

        // Create panel for division radio buttons
        JPanel divPanel = new JPanel();
        divPanel.add(intDivRadio);
        divPanel.add(realDivRadio);

        // Create panel for calculate button
        JPanel buttonPanel = new JPanel();
        buttonPanel.add(calculateButton);

        // Add panels to main frame
        setLayout(new BorderLayout());
        add(inputPanel, BorderLayout.CENTER);
        add(divPanel, BorderLayout.NORTH);
        add(buttonPanel, BorderLayout.SOUTH);

        pack();
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    public void actionPerformed(ActionEvent e) {
        // Get operands and operators from input fields
        double[] operands = new double[5];
        for (int i = 0; i < operandFields.length; i++) {
            String operandStr = operandFields[i].getText();
            if (operandStr.isEmpty()) {
                JOptionPane.showMessageDialog(this, "Please enter all operands.");
                return;
            }
            try {
                operands[i] = Double.parseDouble(operandStr);
            } catch (NumberFormatException ex) {
                JOptionPane.showMessageDialog(this, "Invalid operand: " + operandStr);
                return;
            }
        }
        char[] operators = new char[4];
        for (int i = 0; i < operatorBoxes.length; i++) {
            operators[i] = ((String)operatorBoxes[i].getSelectedItem()).charAt(0);
        }

        // Calculate result
        double result = operands[0];
        for (int i = 0; i < operators.length; i++) {
            switch (operators[i]) {
                case '+':
                    result += operands[i+1];
                    break;
                case '-':
                    result -= operands[i+1];
                    break;
                case '*':
                    result *= operands[i+1];
                    break;
                case '/':
                    if (operands[i+1] == 0) {
                        JOptionPane.showMessageDialog(this, "Cannot divide by zero.");
                        return;
                    }
                    if (intDivRadio.isSelected()) {
                        result /= operands[i+1];
                        result = (int)result;
                    } else {
                        result /= operands[i+1];
                    }
                    break;
            }
        }

        // Update result field
        resultField.setText(Double.toString(result));
    }

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

此代码使用了文本行数组来存储输入的操作数，并使用组合框来选择运算符。处理除数为零的情况，并提供了整数除和实数除的选项。
