请求Java正则表达式字符串

Question

i was wondering if anybody could help me with a RegEx i need to use for matching strings in the format "4%,6%,8%,9%" "(Number)(Percentage)(comma)(number)(percentage)....N"

I tried hard to get this one ^[\\d*(?:%),]+$ but its matching the format "4%,2,6,5%" (numbers without percentage simbol).

Thanks in advance!

Answer 1

Change your regex like below,

^\d+%(?:,\d+%)+$

(?:,\\d+%)+ Allows one or more strings of this ,<number>% format.

OR

^\d+%(?:,\d+%)*$

(?:,\\d+%)* Allows zero or more strings of this ,<number>% format.
