extract substring in java using regex

Question

I need to extract \"URPlus1_S2_3\" from the string:

\"Last one: http://abc.imp/Basic2#URPlus1_S2_3,\" 

using regular expressi

Answer 1

String s = Last one: http://abc.imp/Basic2#URPlus1_S2_3,"
String result = s.replaceAll(".*#", "");

The above returns the full String in case there's no "#". There are better ways using regex, but the best solution here is using no regex. There are classes URL and URI doing the job.
