Java递归遍历目录的小例子

publicstaticvoidmain(String[]args){

        Filef=newFile("D:\\test\\fsd");
        listChids(f,0);

    }

    publicstaticvoidlistChids(Filef,intlevel){

        StringpreSrt="";
        for(inti=0;i<level;i++){

            preSrt+="----";
        }

        System.out.println(preSrt+f.getName());

        if(!f.isDirectory()){

            return;
        }else{

            File[]fs=f.listFiles();
            for(inti=0;i<fs.length;i++){

                listChids(fs[i],level+1);
            }
        }
    }
