I have an array of Pairs.
The first value in the Pair represents coefficient of a polynomial, and the second represents the power of the polynomial.
How can I sort it in a descending order without creating a long code?
Someone here recommended me to use Collections.sort() on the array of Pairs, but I don't understand how it's possible to do this on this array, since it doesn't represent a list, so it's impossible to sort it.
I obviously need to sort it by the powers value, but how it's possible to do this and change the coefficient's indices in accordance with the power parameter?
Thank you!

I already put inside the Pairts the 2 different arrays, now everything is mixed up and I need to sort them
Exactly
Pairs = [[7,3], [5,4], [8,6], [9,2]]
it looks something like this
I need to sort it to be like this:
Pairs = [[8,6], [5,4], [7,3 ], [9,2]]

I'm sorry, I wasn't home for few hours, I'll save it and try to finish it tomorrow.
I'll sit the whole day tomorrow to do this
Thank you very much ❤️
