StringBuffer performance

In the below code, I wanted to check the time taken by StringBuffer to do a concatination, by passing the string in two different ways. I got 750ms and 450ms respectively. What is wrong in passing the string in my second approach?Would be nice if anyone explains me theory behind this. Thanks a lot.

What result did you expect? You do the costly string concatenation in line 16 before handing over the concatenated string to the StringBuffer. So no surprise it is slower.
