好吧，我唯一的问题是打开的对话框是先显示的。我只想把它放在 JFrame 然后把剩下的放在房间里 JFrame 喜欢打开图像并显示它。应该是这样的
问题是我的 JFileChooser 先放映。还有一件事是我希望这一切都在jframe内，就像图中所示。
这是我的密码：

import java.awt.Image;
import java.io.File;
import javax.swing.*;
import javax.swing.filechooser.FileNameExtensionFilter;
import javax.swing.border.*;

import java.awt.Color;
import java.awt.Dimension;

public class imgviewer extends JFrame{

    JButton button;
    JLabel label;

    public imgviewer() {
        super("Image viewer");
        label = new JLabel();
        label.setBounds(400, 10, 180, 300);
        Border b = BorderFactory.createLineBorder(Color.ORANGE, 2);
        JFileChooser file = new JFileChooser(".");
        label.setBorder(b);
        add(label);
        file.setPreferredSize(new Dimension(400, 300));

        file.setCurrentDirectory(new File(System.getProperty("user.home")));
        FileNameExtensionFilter filter = new FileNameExtensionFilter("*.Images", "jpg", "png", "gif");
        file.addChoosableFileFilter(filter);
            int result = file.showOpenDialog(null);
            if (result == JFileChooser.APPROVE_OPTION) {
                File selectedFile = file.getSelectedFile();
                String path = selectedFile.getAbsolutePath();
                label.setIcon(ResizeImage(path));
            }

            else if (result == JFileChooser.CANCEL_OPTION) {
                System.out.println("No File Selected");
            }

        add(file);
        setLayout(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        setSize(600, 350);
        setVisible(true);
    }

     public ImageIcon ResizeImage(String ImagePath) {
         ImageIcon MyImage = new ImageIcon(ImagePath);
         Image img = MyImage.getImage();
         Image newImg = img.getScaledInstance(label.getWidth(), label.getHeight(), Image.SCALE_SMOOTH);
         ImageIcon image = new ImageIcon(newImg);
         return image;
     }

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