Examples of jodd.util.StringBand

jodd.util.StringBand
StringBand is a faster alternative to StringBuilder. Instead of adding strings, they are stored in an internal array. Only at the end of concatenation, when toString() is invoked, strings are joined together in a very fast manner.
To make StringBand even faster, predict the number of joined strings (and not the final string size)!
