Hi, there! I am checking the password (type string) for hardness, the constrain is to collect letters with different register and integers together in one string (password). I am doing in this way, but it doesn't work:

'adaAWDD123'.matches('[A-Z]*[a-z]*[0-9]*')

It would be not true...Could you help me with it?

Your question is about how to use regular expressions. That's not
Eclipse-specific. Better to Google and then use Stackoverflow... Your
pattern doesn't match because it allows only upper case letters followed
by lower case letters followed by numbers, any or all of which can be
absent, but the string starts with lower case letters and upper case
letters aren't allowed after that.
