Help StringUtil.concat aCis

[l2jkain]

There is no such thing right now? How do I make my mistake I have to create this?

Use regular String concatenation, "+" operator. It will be translated automatically into StringBuilder.

 

The only rule is to avoid to concatenate strings inside a for loop, use a StringBuilder and StringUtil.append if that happens. There is shitload amount of exemples over sources.
