针对特定扩展的Java路径过滤

import java.io.File;
import java.io.FilenameFilter;

public class ExtensionFilterExample {
    public static void main(String[] args) {
        String directory = "/path/to/directory"; // 待过滤的目录路径
        String extension = ".txt"; // 特定扩展名

        File dir = new File(directory);
        File[] files = dir.listFiles(new FilenameFilter() {
            @Override
            public boolean accept(File dir, String name) {
                return name.toLowerCase().endsWith(extension);
            }
        });

        if (files != null) {
            for (File file : files) {
                System.out.println(file.getName());
            }
        }
    }
}
