Introducing concat – pretty Apex string builder for Salesforce/Force.com

Concatenating strings in Apex with "+" operator  or String.join() can be full of pain. Unwanted spaces and commas. Empty or null strings. Ugly cascades of checks. Familiar?

Concat provides a solution!

It's key features are:

• Null- and empty string safe
• Clear chaining syntax

 

String result = 

concat.strings('Apex', 'can', 'be').add('less').add('').

       add(null).add('painful').with('-').end('!');

Pretty easy, huh?
