今天编程有点问题，是我基础打的不好。还请个位高人多多指教把正确的方法帮我写上，我仅仅是一个初学者
谢谢！ Smile

下面是程序
public class CharChange
{
  public static void main(String[]args)
  {
    char a1;
    a1=(char)System.in.read();
    try
    {
      if(a1>A&&a1<Z)
    }
    catch(Exception e)
    {
      System.out.print("异常信息:"+a1+"您输入的不是大写字母");
    }
  }
}
Beer

下面是出现的错误：
Chatchange.java:10: 非法的表达式开始
}

Posted by: JiafanZhou Posted on: 2007-10-27 21:05 You are actually wasting my time here to look at this "problem"!! This type of mistake should not be forgiven!! I propose that you should really learn Java syntax thoroughly. I know you may just be a novice, buta... even this, I don't think you know programming at all! Regards, Jiafan
