Exclude a certain number from this regex



I have this regex that test for an input with max length of 5. My problem is I want to exclude the single digit of 2. If string contains only number "2", it should fail. How do I exclude number 2 in this regex? /^([a-zA-Z,\d]){1,5}$/












13425 - Match


03277 - Match


2 - Fail.

  1. A negative look-ahead assertion can do this for you

    /^(?!2$)([a-zA-Z,\d]){1,5}$/

Slow Android emulator

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
