Question

I am not posting any code I am struck with. I am trying this in Java:

Issue:

I have words like:

,xxxx-1223
yyyyy,xxdd-345
$,xxxxr-7
sdsdsdd-18

so what ever format I have I should be able to read the last one:

xxxx-1223
xxdd-345
xxxxr-7
sdsdsdd-18

what so may be the words, all I need to to get the words as shown.

Answer 1

Use String#lastIndexOf(int) to find where the last comma occurs, and use String#substring(int) to get the rest of the string that follows.

String input = /* whatever */;
int lastComma = input.lastIndexOf(',');
String output = input.substring(lastComma + 1);
