Collections vs Arrays regarding sort() What is the difference between these two regarding sort() method? I know Arrays' sort() is using binary search for sort(), what about Collections'? And how to choose which to use? Thanks!
Well, besides operating on different stuff (Collections.sort
operates on a List
, and Arrays.sort
operates on an array), java.util.Collections.sort()
simply calls java.util.Arrays.sort()
to do the heavy lifting.
Also, for what it's worth, notice that Arrays.sort
runs a merge sort.
