java - Alphabetical sort arraylist -

i have string arraylist, need sort list in alphabetical order. logic needs ignore lowercase versus uppercase, punctuation (e.g. periods, dashes).

example: incorrect: t-ext, tabc (text), te text

correct: tabc (text), t-ext, te text

first iterate through list , rid of character dont want part of ordering. second call sort on collection, or collections.sort(list,comparator) custom comparator. can rid of unwanted characters in comparator method if want keep original is.
