java - Writing regex for string containing no only numbers -

-

i need write regex containing not digits [0-9]. how can without explicitly specifying possible charaters in group. possible through lookahead/lookbehind? examples:

034987694 - doesn't match 23984576s9879 - match rtfsdbhkjdfg - match =-0io[-09uhidkbf - match 9347659837564983467 - doesn't match 

^(?!\\d+$).*$

this should you.see demo.

the negative lookahead check if string doesnt have integers start end.you need $ make sure check till end or else check @ start.
