Need to add & symbol before last word in the string!!!

Hello Everyone,

I had small query

Example 1 :
i have a string = Mom, Dad, Son, Daughter
i want a string = Mom, Dad, Son & Daughter

Example 2 :
i have a string = Mom, Dad, Son
i want a string = Mom, Dad & Son

Please help me to provide a solution for this.

Hi Azar,
If your use case is to always replace the last separating comma in your string, you can use something like this:
String a = 'Mom, Dad, Son, Daughter';
String newString = a.reverse().replaceFirst(',', ' &').reverse();
