How do i arrange 3 random digits in desending order

Hi, i'm new to this site and Java, obviously.

I've been frustrated for a while now on this. For a class assignment, i have to create a user input where someone can input 3 digits in any order, to then have the function output them from greatest to least. I feel like a understand user input, i just don't know how to have java output numbers from decending order. I've seen a couple of options online by using the 'swapping method' but only with two integers. IF someone could help i would appreciate it. Thanks.
