Question

I need help understanding the below java code. We are not allow to use in our class the ArrayList sort method, so our professor provided us with an alternative. Suppose that I have an ArrayList<Integer> n, that contains the following values: 10, 30, 40, 50, 80, 90. Based of the code below, are the following initial values correct:

n.get(i) = 10,

n.get(j) = 40,

n.get(jMin) = 30,

Please kindly comment the code below. If possible, please draw the interpretation of this code on a piece of paper and attach it to the answer. Thank you in advace for your assistance!

public static void sort(ArrayList<Integer> n) {

        for (int i = 0; i < n.size() - 1; i = i + 1) {

            int jMin = i + 1;
          
            for (int j = i + 2; j < n.size(); j = j + 1)

                  // Is n.get(j) = 40 and n.get(jMin) = 30 in the first loop?
                if (n.get(j) < n.get(jMin))
                    jMin = j;

                 // // Is n.get(i) = 10 and n.get(jMin) = 30 in the first loop?
            if (n.get(i) > n.get(jMin)) {

                int t = n.get(i);
                n.set(i, n.get(jMin));
                n.set(jMin, t);
            }
        }
    }

Explanation / Answer

The following staemnet from the code is tobe corrected.

// // Is n.get(i) = 10 and n.get(jMin) = 30 in the first loop?
