Hello Everybody,

I am java newbie preparing for scjp 5. I started my prep with K&B chap 6. I am at regex.



I am not able to figure out why this would not match any x's. Could anybody please clarify. Thanks for help.

Hi Anu, welcome to javaranch.

Well when you use the *? reluctant quantifier, then as its name suggests, it will try to match as less as possible. This kind of things have been asked many times before. Maybe these few discussions might clear your doubt

If you still have doubts, then please ask...
