Java 删除目录

import java.io.File;

public class DelDir {
    public static void main(String[] args) {
        delDir(new File("/home/huanyu/Desktop/a")); //如果文件里还有内容，则递归删除
    }

    public static boolean delDir(File dir){
        if (dir.isDirectory()){
            String[] children = dir.list();
            for (int i=0; i<children.length;i++) {
                boolean success = delDir(new File(dir, children[i]));
                if (!success)
                    return false;
            }

        }
        if (dir.delete()){
            System.out.println("目录已删除！！！");
            return true;
        }else {
            System.out.println("目录删除失败！！！！！");
        }
        return false;
    }
