Shell Sort Sorting algorithms such as InPlaceMergeSort, InsertionSort, and ShellSort perform set operations rather than swap operations. For this reason, the ISwap interface includes two "Set" methods. If you aren't using one of the algorithms that uses a setter, then you can ignore them. ...

It's truer today than it was four years ago, and more true for Java developers than it was for C. Most performance tuning reminds me of the old joke about the guy who's looking for his keys in the kitchen even though he lost them in the street, because the light's better in the...
