Question

I want to remove comma at end if string ends with comma

i need to remove last comma if string ends with ","

Answer 1

You could try a regular expression:

names = names.replaceAll(",$", ""); 

Or a simple substring:

if (names.endsWith(",")) {   names = names.substring(0, names.length() - 1); }
