Write a method, public static void selectSort(ArrayList list), which implements a selection sort on the ArrayList of Integer objects list. For example, if the parameter list would be printed as [3, 7, 2, 9, 1, 7] before a call to selectSort, it would be printed as [1, 2, 3, 7, 7, 9] after the method call.

Explanation:

The following code is written in Java and like asked in the question, it is a function that takes in an ArrayList of Integers as a parameter and uses selection sort to sort the array.

public static void selectSort(ArrayList<Integer> list) {

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

                       {

                               int index = i;

                               for (int j = i + 1; j < list.size(); j++){

                                       if (list.get(j) < list.get(index)){

                                               index = j;

                                       }

                               }

                               int smallerNumber = list.get(index);

                               list.set(index, list.get(i));

                               list.set(i, smallerNumber);

                       }

               }
