扫描仪出错：java输入不匹配异常

希望你能给我一些好的建议：我有一个游戏，我需要玩家输入名字，但它只允许一个单词。如果用户输入超过1个单词，程序将给出javamismatchexception错误并关闭程序是否有办法允许用户输入多个单词作为自己的名字？提前感谢！我为底部的文字混乱道歉。我是这个网站的新用户，它说我已经将代码缩进了4个空格，但并没有正确显示

在.nextLine（）中使用

而不是
next（）
作为名称。太棒了！我不知道你能做到。谢谢@Codebender@AArisso有时，阅读Javadoc会带来回报：

        playerClass = in.nextInt();
        if (playerClass == 1 || playerClass == 2 || playerClass == 3)
