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);

    }
