用java删除文件夹里的所有文件

import java.io.File;




public class Test


{


public static void main(String args[]){


Test t = new Test();


delFolder("c:/bb");


System.out.println("deleted

");


}




//删除文件夹


//param folderPath 文件夹完整绝对路径




public static void delFolder(String folderPath) {


try {


delAllFile(folderPath); //删除完里面所有内容


String filePath = folderPath;


filePath = filePath.toString();


java.io.File myFilePath = new java.io.File(filePath);


myFilePath.delete(); //删除空文件夹


} catch (Exception e) {


e.printStackTrace();


}


}




//删除指定文件夹下所有文件


//param path 文件夹完整绝对路径


public static boolean delAllFile(String path) {


boolean flag = false;


File file = new File(path);


if (!file.exists()) {


return flag;


}


if (!file.isDirectory()) {


return flag;


}


String[] tempList = file.list();


File temp = null;


for (int i = 0; i < tempList.length; i++) {


if (path.endsWith(File.separator)) {


temp = new File(path + tempList[i]);


} else {


temp = new File(path + File.separator + tempList[i]);


}


if (temp.isFile()) {


temp.delete();


}


if (temp.isDirectory()) {


delAllFile(path + "/" + tempList[i]);//先删除文件夹里面的文件


delFolder(path + "/" + tempList[i]);//再删除空文件夹


flag = true;


}


}


return flag;


}


}
