How to find all occurrences of $ which are not escaped or preceded by \ in java

Test Cases :

  1. he is having $money 500
  2. he is having \$money 500
  3. $
  4. \$

Matches should be the 1st & 3rd one, since 2nd & 4th already contains escaped "$".

I tried - Pattern pattern=Pattern.compile("(^\\\\$)"); but it doesn't match any. Please help.

You can use Negative Lookbehind here to exclude the already escaped $ characters.

(?<!\\\\)\\$
