Java文件操作

还是毕业设计要用到,存这里,慢慢更新.

①JAVA创建文件夹

/**
  * 用于创建文件夹的方法
  * @param mkdirName
  */
 public void mkdir(String mkdirName)
 {
     try
     {
         File  dirFile = new File(mkdirName);
         boolean bFile   = dirFile.exists();
         if( bFile == true )
         {
            System.out.println("The folder exists.");
         }
         else
         {
            System.out.println("The folder do  not exist,now trying to create a one...");

            bFile = dirFile.mkdir();
            if( bFile == true )
            {
               System.out.println("Create successfully!");
               System.out.println("创建文件夹");
            }
            else
            {
                System.out.println("Disable to make the folder,please check the disk is full or not.");
                System.out.println(" 文件夹创建失败，清确认磁盘没有写保护并且空件足够");
                System.exit(1);
            }
         }
     }
     catch(Exception err)
     {
         System.err.println("ELS - Chart : 文件夹创建发生异常");
         err.printStackTrace();
     }
 }
}
