File[] files=dir.listFiles();for(inti=0;i<files.length;i++){if(files[i].isDirectory()){//这里面用了递归的算法getAllFileSize(files[i]); }else{ sum+=files[i].length(); System.out.println(files[i]+"的大小:"+files[i].length()); ...
for(File f : subfiles) { if(f.isDirectory) {// 文件目录 printSubFile(f); }else{// 文件 System.out.println(f.getAbsolutePath); } } } // 方式二:循环实现 // 列出file目录的下级内容,仅列出一级的话 // 使用File类的String[] list比较简单 ...
