1. First word should contain only [0-9a-zA-Z]
2. Second word can contain any of these characters[0-9a-zA-Z],space,"_" and "-".But same characters(space,"_" and "-") cannot be consicutive.For examples "__","--"," ","_-" are invalid.But "- _" is valid.
3.
i) Hello world_-(invalid)
ii) Hello world_ -(valid)
iii) Hello world--(invalid)
iv) Hello world- -(valid)
v) Hello world_ _(valid)
vi) Hello world(invalid) - 2 spaces

It would also be nice to see the relevant piece of code.



Thanks for your reply.This is the code used for validating the string.


Also, as far as I can see, the pattern will allow something like "a_ - _ _ -". Is that what you want?


yes this is a valid input.

Hi All,
I am new to Java Regular expression. We are using a pattern for matching a string. We are using this for validating a text field and it meets our requirements. But there is a performance issue in the matching.
pattern [a-zA-Z0-9]+[ ]?(([_\-][a-zA-Z0-9 ])*)?[_\-]?)+

1. Input text should start with a-zA-Z0-9.
2. Space(single) is allowed between words
3. "_" and "-" are allowed but cannot be consecutive.

Our problem is, for certain input strings the CPU time goes high and causes hanging the threads. Also we get exceptions. Can anyone please
help me to optimize the Pattern or suggest a new pattern to solve my issue.
