How to find multiples of the same integer in an arraylist?
- by Dan
Hi
My problem is as follows. I have an arraylist of integers. The arraylist contains 5 ints e.g[5,5,3,3,9] or perhaps [2,2,2,2,7]. Many of the arraylists have duplicate values and i'm unsure how to count how many of each of the values exist.
The problem is how to find the duplicate values in the arraylist and count how many of that particular…
