     See Marcel Muller's response.  As a practical matter, use
java.util.Collections#sort or java.util.Arrays#sort and apply
your ingenuity to the other problems your program needs to solve.
Later on, if you measure the performance, find it inadequate,
discover that sorting is a significant time-waster, *and* think
you can do better -- if all those, then and only then implement
your own sort.

     Not even close.  One well-known far worse sort is

	https://en.wikipedia.org/wiki/Bogosort

... and of course any implementation of any algorithm can always
be disimproved.  (One effective way is to post the bad code to
Usenet and solicit improvements ;)
