如何在Java中迭代读取目录中的所有文件？

import java.io.File;

public class FileIterator {
    public static void main(String[] args) {
        String directoryPath = "目录路径";
        File directory = new File(directoryPath);
        iterateFiles(directory);
    }

    public static void iterateFiles(File directory) {
        if (directory.isDirectory()) {
            File[] files = directory.listFiles();
            if (files != null) {
                for (File file : files) {
                    if (file.isDirectory()) {
                        iterateFiles(file);
                    } else {
                        // 处理文件
                        System.out.println(file.getAbsolutePath());
                    }
                }
            }
        }
    }
}
