[英]String pattern which starts with # @ and can contain underscore and minus
I try to make a string pattern that can contain UTF-8 characters (öäå, etc) and match the following criteria in Java (1.7);我尝试制作一个可以包含 UTF-8 字符(öäå 等)的字符串模式,并在 Java (1.7) 中符合以下条件;
What I have at the moment that works but are missing many of the criteria.我目前所拥有的有效但缺少许多标准。
"#\\p{javaLowerCase}+"
"#\\p{javaLowerCase}+"
I don't know how to complete and add the rest of the criteria.我不知道如何完成和添加其余的标准。 How would a regex expression look like that can accommodate the criteria I have?
一个正则表达式看起来如何才能满足我的标准?
This translates into a regex in a relatively simple way:这以一种相对简单的方式转化为正则表达式:
"[#@][\\p{javaLowerCase}\\d_-]{2,14}"
This translates the "Min 3 and maximum 15 characters" inclusive of the #
or @
at the beginning.这将翻译“最少 3 个和最多 15 个字符”,包括开头的
#
或@
。 If these should not be counted, change the suffix to {3,15}
.如果这些不应计算在内,请将后缀更改为
{3,15}
。
