计算器静态界面设计java代码

以下是一个简单的计算器静态界面的Java代码：

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

public class CalculatorGUI extends JFrame {
    private JPanel mainPanel;
    private JTextField inputField;
    private JButton button0;
    private JButton button1;
    private JButton button2;
    private JButton button3;
    private JButton button4;
    private JButton button5;
    private JButton button6;
    private JButton button7;
    private JButton button8;
    private JButton button9;
    private JButton buttonAdd;
    private JButton buttonSubtract;
    private JButton buttonMultiply;
    private JButton buttonDivide;
    private JButton buttonEquals;
    private JButton buttonClear;

    public CalculatorGUI() {
        setTitle("Calculator");
        setSize(300, 400);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);

        mainPanel = new JPanel(new BorderLayout());
        inputField = new JTextField();
        inputField.setHorizontalAlignment(JTextField.RIGHT);
        inputField.setPreferredSize(new Dimension(300, 50));

        JPanel buttonPanel = new JPanel(new GridLayout(4, 4));
        button0 = new JButton("0");
        button1 = new JButton("1");
        button2 = new JButton("2");
        button3 = new JButton("3");
        button4 = new JButton("4");
        button5 = new JButton("5");
        button6 = new JButton("6");
        button7 = new JButton("7");
        button8 = new JButton("8");
        button9 = new JButton("9");
        buttonAdd = new JButton("+");
        buttonSubtract = new JButton("-");
        buttonMultiply = new JButton("*");
        buttonDivide = new JButton("/");
        buttonEquals = new JButton("=");
        buttonClear = new JButton("C");

        buttonPanel.add(button7);
        buttonPanel.add(button8);
        buttonPanel.add(button9);
        buttonPanel.add(buttonAdd);
        buttonPanel.add(button4);
        buttonPanel.add(button5);
        buttonPanel.add(button6);
        buttonPanel.add(buttonSubtract);
        buttonPanel.add(button1);
        buttonPanel.add(button2);
        buttonPanel.add(button3);
        buttonPanel.add(buttonMultiply);
        buttonPanel.add(buttonClear);
        buttonPanel.add(button0);
        buttonPanel.add(buttonEquals);
        buttonPanel.add(buttonDivide);

        mainPanel.add(inputField, BorderLayout.NORTH);
        mainPanel.add(buttonPanel, BorderLayout.CENTER);

        setContentPane(mainPanel);
        setVisible(true);
    }

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

上述代码使用了Java Swing GUI库来创建计算器的静态界面。界面包括一个文本框和各种按钮，通过布局管理器将它们放置在合适的位置。用户可以通过按钮输入数字和运算符，计算器会在文本框中显示计算结果。
