帮我写一个完整的这个图片查看器的程序

由于编写一个完整的Java Swing应用程序涉及到很多代码，这里我将给出一个简化版的基本框架，你可以基于此构建一个基本的图片查看器。首先确保已导入必要的库：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;

public class ImageViewer extends JFrame implements ActionListener {
    private JButton openButton, prevButton, nextButton;
    private JLabel imageView;
    private ArrayList<String> imagesList;
    private int currentIndex = 0;
    
    public ImageViewer() {
        // 设置窗口属性
        setTitle("图片查看器");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(800, 600);

        // 初始化控件和成员变量
        initComponents();
        
        // 显示第一张图片
        displayCurrentImage(imagesList.get(currentIndex));
    }

    private void initComponents() {
        JPanel panel = new JPanel(new BorderLayout());
        imagesList = new ArrayList<>();

        openButton = new JButton("打开");
        openButton.addActionListener(this);
        prevButton = new JButton("上一张");
        prevButton.addActionListener(this);
        nextButton = new JButton("下一张");
        nextButton.addActionListener(this);
        imageView = new JLabel();

        openButton.setBounds(10, 10, 100, 30);
        prevButton.setBounds(120, 10, 70, 30);
        nextButton.setBounds(210, 10, 70, 30);
        imageView.setBounds(30, 40, 640, 480);

        panel.add(openButton, BorderLayout.WEST);
        panel.add(prevButton, BorderLayout.NORTH);
        panel.add(nextButton, BorderLayout.EAST);
        panel.add(imageView, BorderLayout.CENTER);

        setContentPane(panel);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == openButton) {
            showFileChooser();
        } else if (e.getSource() == prevButton) {
            changeImage(-1);
        } else if (e.getSource() == nextButton) {
            changeImage(1);
        }
    }

    private void showFileChooser() {
        JFileChooser fileChooser = new JFileChooser();
        int result = fileChooser.showOpenDialog(this);
        if (result == JFileChooser.APPROVE_OPTION) {
            File selectedFile = fileChooser.getSelectedFile();
            try {
                String filePath = selectedFile.getAbsolutePath();
                if (!imagesList.contains(filePath)) {
                    imagesList.add(filePath);
                    Collections.sort(imagesList); // 如果有需求，可以排序
                }
                updateImageList();
                displayCurrentImage(filePath);
            } catch (IOException ioe) {
                JOptionPane.showMessageDialog(this, "文件打开失败：" + ioe.getMessage(), "错误", JOptionPane.ERROR_MESSAGE);
            }
        }
    }

    private void updateImageList() {
        // 更新显示图片的数量等信息
    }

    private void displayCurrentImage(String imagePath) {
        try {
            ImageIcon imgIcon = new ImageIcon(imagePath);
            imageView.setIcon(imgIcon);
            if (currentIndex == 0) {
                JOptionPane.showMessageDialog(this, "这是第一张图片");
            } else if (currentIndex == imagesList.size() - 1) {
                JOptionPane.showMessageDialog(this, "这是最后一张图片");
            }
        } catch (IOException ioe) {
            System.out.println("加载图片失败：" + ioe.getMessage());
        }
    }

    private void changeImage(int delta) {
        currentIndex += delta;
        if (currentIndex < 0) {
            currentIndex = 0;
        } else if (currentIndex >= imagesList.size()) {
            currentIndex = imagesList.size() - 1;
        }
        displayCurrentImage(imagesList.get(currentIndex));
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            ImageViewer viewer = new ImageViewer();
            viewer.setVisible(true);
        });
    }
}

这个代码示例包含了一个简单的图片查看器，用户可以选择图片，然后浏览上一张、下一张，并看到当前图片是否是第一张或最后一张。注意，为了保持简洁，这里没有处理文件打开失败的情况以及显示图片数量的信息。在实际应用中，你可能还需要完善错误处理和用户体验。
