如何在JFileChooser中添加“发送到”选项

import javax.swing.filechooser.FileFilter;
import java.io.File;

public class SendToFileFilter extends FileFilter {
    @Override
    public boolean accept(File f) {
        // 判断文件是否为目录或者是以.txt结尾的文件
        return f.isDirectory() || f.getName().toLowerCase().endsWith(".txt");
    }

    @Override
    public String getDescription() {
        return "发送到";
    }
}

import javax.swing.*;
import javax.swing.filechooser.FileFilter;

public class Main {
    public static void main(String[] args) {
        JFileChooser fileChooser = new JFileChooser();
        FileFilter sendToFileFilter = new SendToFileFilter();
        fileChooser.addChoosableFileFilter(sendToFileFilter);

        int result = fileChooser.showOpenDialog(null);
        if (result == JFileChooser.APPROVE_OPTION) {
            // 用户选择了文件
            File selectedFile = fileChooser.getSelectedFile();
            System.out.println("Selected file: " + selectedFile.getAbsolutePath());
        }
    }
}
