Clearing a string buffer/builder after loop

Question

How do you clear the string buffer in Java after a loop so the next iteration uses a clear string buffer?

Answer 1

StringBuffer sb = new SringBuffer();
// do something wiht it
sb = new StringBuffer();

i think this code is faster.

Answer 2

I suggest creating a new StringBuffer (or even better, StringBuilder) for each iteration. The performance difference is really negligible, but your code will be shorter and simpler.
