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

If you just want everything after the #, use split:

String s = "Last one: http://abc.imp/Basic2#URPlus1_S2_3," ;
System.out.println(s.split("#")[1]);

Alternatively, if you want to parse the URI and get the fragment component you can do:

URI u = new URI("http://abc.imp/Basic2#URPlus1_S2_3,");
System.out.println(u.getFragment());
