Java Regex-在字符串中查找特定字符串

Question

I am trying to match a string that start with the set word "hotel", then a hyphen, then a word of any length, then another hyphen and finally a number of any length.

Edit: Dima gave the solution I needed in the comments of this question! Thanks Dima.

Further edit: elaborating on Dima's answer, adding capturing groups making it easier to retrieve the information entered, and correcting the last bit to only accept digits:

^hotel-(.+)-(\\d+)

Answer 1

^hotel-(.)*$

(But hotel-something WILL work, according to your initial statement).

So, if you actually want something like:

hotel-XXXXXX-YYYYYYY

Then the regex is :

^hotel-(.)*-(.)*$

Try a regex online tester like http://www.regextester.com/ .

Answer 2

If you want to match the start of the input, you use ^ .

so if you have ^hotel-\\b , that will force hotel to be at the start of the string.

as a note, you can use $ for the end of the string in a similar way.

Answer 3

\bhotel-[^\s-]+-[^\s-]+\b

\\b means that it should be a word boundery

[^\\s-] means anything but - or whitespace
