无条件地将

DateName

设置为

“thirtyfirst”

，而不管在前面的

if/else

测试链中发生了什么。将上述内容替换为：

} else if (date == 31) ;

DateName = "thirtyfirst" ;

顺便说一句：你应该学会使用数组。这将大大简化你的代码。

这不是一个真正的答案，但我还不能评论

使用日历（我自己通常使用GregorianCalendar）和应用格式可能会更好，这样你就可以整理代码。此外，如果你决定将来以不同的方式显示出生日期，那么重复工作就更少了

---

似乎您对编程有点陌生，因此您可能也会发现“case语句”很有用。您可能还能够更好地发现错误/缺少的块，就像您在这里发布的示例代码中所示。（其他两个答案已经提供了解决方案，因此我不再重复。）

哇……请仅包含与您的问题相关的代码，并查看常见问题解答中的代码格式指南：

} else if (date == 31) {
    DateName = "thirtyfirst" ;
}
