JAVA（MyEclipse）总是报错。请高手指点！

主方法里面不能在定义方法

创新互联公司-专业网站定制、快速模板网站建设、高性价比那曲网站开发、企业建站全套包干低至880元,成熟完善的模板库,直接使用。一站式那曲网站制作公司更省心,省钱,快速模板网站建设找我们，业务覆盖那曲地区。费用合理售后完善，十年实体公司更值得信赖。

也就是不能在方法里面在定义方法

要把其他的方法定义在main方法的外面

定义成static 的可以在main 里直接使用

java的小问题

第一行：提醒用户输入角色值。

第二行：定义了一个int类型的角色值role1，并以用户输入的值为其初始化。

第三行：定义了第二个角色值role2。

第四到第七行是一个循环，其中第五行与第一行类似，让用户输入role2的角色值。并在第六行赋给role2.第七行是判断两个角色是否相同，若相同重新循环，否则继续向下执行。

第八、九行设置角色。

第十行开始游戏。
