是否可以检查字符是否与可能性列表匹配? [英] is it possible to check if a char matches a list of possibilities?

问题描述

例如我知道在检查字符串时，您可以执行类似的操作

For example I know that when checking strings, you can do something like

if (string.matches("a|e|i|o|u|A|E|I|O|U" ) )
{
   // Then do this code.
}

但是有没有办法检查字符是否与可能性列表匹配?还是要一一检查，比如

but is there a way to check if a char matches a list of possibilities? or do I have to check one by one, such as

if(char == a || char == e || char == i )

...等

推荐答案

在 String 中查找 char 时，您可以使用indexOf 方法进行搜索字符串.

You can do something similar when looking for a char in a String, by using the indexOf method to search the string.

if ("aeiouAEIOU".indexOf(aChar) != -1)
