Java array sort descending

Question

With the help of Arrays class, I can sort the array in ascending order. Can anyone tell me is there a way to sort it in descending order?

Answer 1

Check the code implementation below: 

sort(T[] a, Comparator<? super T> c) 

Arrays.sort(a, Collections.reverseOrder());

 

This works with 'Array of Objects' like Integer array. It doesn’t work for a primitive array such as an int array.

If you want to sort a primitive array in descending order, you have to first sort the array in ascending order and then reverse the array. This holds true for two-dimensional primitive arrays as well.
