在java中搜索目录及其子目录中的文件

import java.io.File;

public class FileSearch {
    public static void main(String[] args) {
        String directoryPath = "目录路径";
        String fileName = "文件名";

        File directory = new File(directoryPath);
        if (directory.exists()) {
            searchFiles(directory, fileName);
        } else {
            System.out.println("目录不存在！");
        }
    }

    public static void searchFiles(File directory, String fileName) {
        File[] files = directory.listFiles();
        if (files != null) {
            for (File file : files) {
                if (file.isDirectory()) {
                    searchFiles(file, fileName); // 递归调用
                } else if (file.getName().equalsIgnoreCase(fileName)) {
                    System.out.println("找到文件：" + file.getAbsolutePath());
                }
            }
        }
    }
}
