用JAVA语言写一个图形界面化复杂计算器

好的，我可以回答这个问题。要实现一个图形界面化复杂计算器，可以使用Java Swing库来创建GUI界面，然后使用Java的数学库来实现计算器的功能。可以使用文本框和按钮来实现用户输入和计算结果的显示，还可以添加菜单栏和工具栏来增强用户体验。具体实现细节可以参考Java Swing的官方文档和示例代码。

用java语言写一个图形界面化可以实现混合运算的计算器

好的，以下是一个简单的Java图形界面计算器的代码：

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

public class Calculator extends JFrame implements ActionListener {

    private JTextField display;
    private JButton[] buttons;
    private String[] buttonLabels = {"7", "8", "9", "/", "4", "5", "6", "*", "1", "2", "3", "-", "0", ".", "=", "+"};
    private double operand1, operand2;
    private String operator;

    public Calculator() {
        super("Calculator");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(300, 300);
        setLayout(new BorderLayout());

        display = new JTextField();
        display.setEditable(false);
        add(display, BorderLayout.NORTH);

        JPanel buttonPanel = new JPanel();
        buttonPanel.setLayout(new GridLayout(4, 4));

        buttons = new JButton[16];
        for (int i = 0; i < 16; i++) {
            buttons[i] = new JButton(buttonLabels[i]);
            buttons[i].addActionListener(this);
            buttonPanel.add(buttons[i]);
        }

        add(buttonPanel, BorderLayout.CENTER);

        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        String label = e.getActionCommand();

        if (label.equals("C")) {
            display.setText("");
        } else if (label.equals("=")) {
            operand2 = Double.parseDouble(display.getText());
            double result = 0;

            if (operator.equals("+")) {
                result = operand1 + operand2;
            } else if (operator.equals("-")) {
                result = operand1 - operand2;
            } else if (operator.equals("*")) {
                result = operand1 * operand2;
            } else if (operator.equals("/")) {
                result = operand1 / operand2;
            }

            display.setText("" + result);
        } else if (label.equals("+") || label.equals("-") || label.equals("*") || label.equals("/")) {
            operand1 = Double.parseDouble(display.getText());
            operator = label;
            display.setText("");
        } else {
            display.setText(display.getText() + label);
        }
    }

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

这个计算器可以进行加、减、乘、除四种混合运算，支持小数点输入和清空操作。
