java删除文件夹

用递归实现的删除文件夹，很简单，功能也很强，非空文件夹也能删除！


package file;




import java.io.File;






public class DeleteAllFile ...{




public static void main(String args[]) ...{


clearTmpFile(new File("c:/forLiu"));


}






private static void clearTmpFile(File tmpFile) ...{




if (!tmpFile.exists()) ...{


System.out.println("file is not exist!");


return;


}




if (tmpFile.isDirectory()) ...{


File[] fileList = tmpFile.listFiles();




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




if (fileList[i].isDirectory()) ...{


clearTmpFile(fileList[i]);


}




if (fileList[i].delete()) ...{


System.out.println("Temp file:""


+ fileList[i].getAbsolutePath()


+ "" has been deleted.");


}


}




if (tmpFile.delete()) ...{


System.out.println("Temp file:"" + tmpFile.getAbsolutePath()


+ "" has been deleted.");


}




} else ...{




if (tmpFile.delete()) ...{


System.out.println("Temp file:"" + tmpFile.getAbsolutePath()


+ "" has been deleted.");


}


}


}


}
