java建立檔案夾

用java建立檔案夾

package test;

public class muluTest
{
 public static void main(String[] args)
 {
  muluTest mulutest = new muluTest();
  mulutest.newFolder("D:\\abcds");
 }
 public   void   newFolder(String  folderPath)
 {
  String   filePath   =   folderPath;
  filePath   =  filePath.toString();    
  java.io.File   myFilePath  =   new   java.io.File(filePath);
  try
  {
   if(myFilePath.isDirectory())
   {
    System.out.println("the directory isexists!");
   }
   else
   {
    myFilePath.mkdir();
    System.out.println("建立目錄成功");
   }
  }
  catch   (Exception   e)
  {
   System.out.println("建立目錄操作出錯");
   e.printStackTrace();
  }
 }
}
