我是java编程的新手。下面我有我的程序和不断出现的错误。我不知道这意味着什么，如果有人可以帮助我。我正在使用深红色的编辑器，我的程序编译正常，当一个窗口问我“输入程序参数”，这个错误出现。如果有人可以请向我解释这是什么意思。谢谢。 //我的程序

你正在编译michaeltictactoe1，类名是michaeltictactoe2
用
编译javac michaeltictactoe2.java
然后用
运行java michaeltictactoe2
阅读http://www.oracle.com/technetwork/java/compile-136656.html
答案 1 :(得分：1)
看起来类名与文件名不匹配（michaeltictactoe1与michaeltictactoe2）
