参考下面程序实现猜大小的游戏，有两个按钮，分别表示用户猜大还是猜小，代码内部随机产生一个0-9的数，如果产生的数0-4为小，5-9为大。显示用户是否猜对，并告诉用户正确的数字大小。。import java.awt.Color;

抱歉，我是一个自然语言处理AI，不具备编写代码的能力。但是，我可以为你提供一份Java代码，实现你所描述的猜大小游戏：

import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;

public class GuessNumberGame extends JFrame implements ActionListener {
    private JLabel labelTitle;
    private JLabel labelNumber;
    private JButton buttonGuessSmall;
    private JButton buttonGuessBig;

    private Random random;
    private int targetNumber;

    public GuessNumberGame() {
        super("Guess Number Game");
        setLayout(new FlowLayout());

        labelTitle = new JLabel("Guess Number Game");
        labelTitle.setFont(new Font("Arial", Font.BOLD, 24));
        labelTitle.setForeground(Color.BLUE);
        add(labelTitle);

        labelNumber = new JLabel("");
        labelNumber.setFont(new Font("Arial", Font.PLAIN, 20));
        add(labelNumber);

        buttonGuessSmall = new JButton("Guess Small");
        buttonGuessSmall.addActionListener(this);
        add(buttonGuessSmall);

        buttonGuessBig = new JButton("Guess Big");
        buttonGuessBig.addActionListener(this);
        add(buttonGuessBig);

        setSize(400, 150);
        setVisible(true);

        random = new Random();
        targetNumber = random.nextInt(10);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == buttonGuessSmall) {
            if (targetNumber >= 0 && targetNumber <= 4) {
                JOptionPane.showMessageDialog(this, "Congratulations! You guessed right!");
            } else {
                JOptionPane.showMessageDialog(this, "Sorry, the answer is " + targetNumber + ". You guessed wrong.");
            }
        } else if (e.getSource() == buttonGuessBig) {
            if (targetNumber >= 5 && targetNumber <= 9) {
                JOptionPane.showMessageDialog(this, "Congratulations! You guessed right!");
            } else {
                JOptionPane.showMessageDialog(this, "Sorry, the answer is " + targetNumber + ". You guessed wrong.");
            }
        }
    }

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

这个程序使用Java Swing库实现了一个简单的GUI界面，包含了标题、显示结果的标签、两个按钮。当用户点击按钮时，程序会根据随机生成的数字判断用户的猜测是否正确，并给出相应的提示。
