用JAVA程序编写一下任务：使用综合布局，设计计算机界面

好的，我可以为您提供一些基本的Java代码，来实现使用综合布局设计计算机界面。您可以根据自己的需求进行修改和扩展。

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

public class CalculatorGUI extends JFrame {
    
    private JPanel mainPanel;
    private JTextField inputField;
    private JButton button1, button2, button3, button4, button5, button6, button7, button8, button9, button0, addButton, subButton, mulButton, divButton, equalButton, clearButton;
    
    public CalculatorGUI() {
        super("Calculator");
        setSize(300,300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        mainPanel = new JPanel(new GridLayout(5,4,5,5));
        inputField = new JTextField();
        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");
        button0 = new JButton("0");
        addButton = new JButton("+");
        subButton = new JButton("-");
        mulButton = new JButton("*");
        divButton = new JButton("/");
        equalButton = new JButton("=");
        clearButton = new JButton("C");
        
        mainPanel.add(button7);
        mainPanel.add(button8);
        mainPanel.add(button9);
        mainPanel.add(divButton);
        mainPanel.add(button4);
        mainPanel.add(button5);
        mainPanel.add(button6);
        mainPanel.add(mulButton);
        mainPanel.add(button1);
        mainPanel.add(button2);
        mainPanel.add(button3);
        mainPanel.add(subButton);
        mainPanel.add(button0);
        mainPanel.add(addButton);
        mainPanel.add(equalButton);
        mainPanel.add(clearButton);
        
        setLayout(new BorderLayout());
        add(inputField, BorderLayout.NORTH);
        add(mainPanel, BorderLayout.CENTER);
        
        setVisible(true);
    }
    
    public static void main(String[] args) {
        new CalculatorGUI();
    }
}

这段代码创建了一个计算器的界面，使用了Java的Swing库，利用BorderLayout和GridLayout布局来实现。您可以运行代码，查看效果，然后根据您的需求进行修改和扩展。
