我添加了一些格式.
谁应该读这个书?
请使用一些进口. Eclipse和/或Netbeans将在此方面为您提供指导.
当从编码中删除了一些错误的字符时，它可以工作-不知道在C& P的过程中是否确实发生过这种情况.
I added some format.
Who is supposed to read this?
Please use some imports. Eclipse and/or Netbeans will guide you in this.
It works when some false characters are removed from the coding - don''t know if that did happen while C&P this.
