遍历某个目录路径下的所有文件并打印输出：
package com.led.file; import java.io.File; public class File_List { public static void listFiles(File file){ if(file!=null){ if(file.isDirectory()){//是目录 File[] f=file.listFiles(); if(f!=null){ for(int i=0;i<f.length;i++){ listFiles(f[i]);//递归调用遍历文件 } } }else{//是文件 System.out.println(file);//打印文件路径 } } } public static void main(String[] args) { File file=new File("E://迅雷下载//mysql-connector-java-3.1.12"); listFiles(file); } }
