Apex String Split with single quotes

Question

I have a String array as follows

String [] toAddress = new String [] {'[email protected]','[email protected]','[email protected]'};

I would like to get the output as

'[email protected]','[email protected]','[email protected]'.

Could you please give some direction on how to achieve this?

Answer 1

You can use String#join to get the output you want:

String result = '\''+String.join(toAddress,'\',\'')+'\'';

This will result in a single string with quoted addresses.
