Answer 1

Jakarta Commons StringUtils.abbreviate(). If, for some reason you don't want to use a 3rd-party library, at least copy the source code.

One big benefit of this over the other answers to date is that it won't throw if you pass in a null.

Answer 2

StringUtils.abbreviate("abcdefg", 6);

This will give you the following result: abc...

Where 6 is the needed length, and "abcdefg" is the string that needs to be abbrevieted.
