java语言完成基础任务三：设计简易计算器软件 1.使用Java图形界面组件设计软件，界面如满足基本的“加、减、乘、除”等运算要求。

好的，以下是一个简单的Java图形界面计算器的代码实现：

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

public class Calculator extends JFrame implements ActionListener {

    private JTextField inputField; // 输入框
    private JButton addButton, subButton, mulButton, divButton; // 四则运算按钮
    private JButton equalButton, clearButton; // 等号和清除按钮

    private double num1, num2, result; // 运算数和结果
    private String operator; // 运算符

    public Calculator() {
        setTitle("简易计算器");
        setSize(300, 200);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // 创建输入框和按钮
        inputField = new JTextField(16);
        addButton = new JButton("+");
        subButton = new JButton("-");
        mulButton = new JButton("*");
        divButton = new JButton("/");
        equalButton = new JButton("=");
        clearButton = new JButton("清除");

        // 设置按钮监听器
        addButton.addActionListener(this);
        subButton.addActionListener(this);
        mulButton.addActionListener(this);
        divButton.addActionListener(this);
        equalButton.addActionListener(this);
        clearButton.addActionListener(this);

        // 添加组件到容器
        Container contentPane = getContentPane();
        contentPane.setLayout(new FlowLayout());
        contentPane.add(inputField);
        contentPane.add(addButton);
        contentPane.add(subButton);
        contentPane.add(mulButton);
        contentPane.add(divButton);
        contentPane.add(equalButton);
        contentPane.add(clearButton);

        setVisible(true);
    }

    public void actionPerformed(ActionEvent event) {
        // 获取输入框中的文本
        String text = inputField.getText();

        // 处理清除按钮事件
        if (event.getSource() == clearButton) {
            inputField.setText("");
            num1 = num2 = result = 0.0;
            operator = null;
            return;
        }

        // 处理数字按钮事件
        try {
            double num = Double.parseDouble(text);
            if (operator == null) {
                num1 = num;
            } else {
                num2 = num;
            }
        } catch (NumberFormatException e) {
            // 忽略非法数字输入
            return;
        }

        // 处理四则运算按钮事件
        if (event.getSource() == addButton) {
            operator = "+";
        } else if (event.getSource() == subButton) {
            operator = "-";
        } else if (event.getSource() == mulButton) {
            operator = "*";
        } else if (event.getSource() == divButton) {
            operator = "/";
        }

        // 处理等号按钮事件
        if (event.getSource() == equalButton) {
            if (operator == null) {
                return;
            }
            switch (operator) {
                case "+":
                    result = num1 + num2;
                    break;
                case "-":
                    result = num1 - num2;
                    break;
                case "*":
                    result = num1 * num2;
                    break;
                case "/":
                    if (num2 == 0.0) {
                        JOptionPane.showMessageDialog(this, "除数不能为零", "错误", JOptionPane.ERROR_MESSAGE);
                        return;
                    }
                    result = num1 / num2;
                    break;
            }
            inputField.setText(Double.toString(result));
            num1 = result;
            num2 = 0.0;
            operator = null;
        }
    }

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

这段代码使用了Java的AWT和Swing图形界面组件库，实现了一个简单的计算器界面，并且支持加、减、乘、除等四则运算。
