After sorted the array you can easily pick up the minimum and maximum value from the sorted array, first element and the last element of the array. For calculate the average you have to use separate method as you used or you can use static variable to calculate the total inside the sorting method. Java ArrayList. The ArrayList class is a resizable array, which can be found in the java.util package. The difference between a built-in array and an ArrayList in Java, is that the size of an array cannot be modified (if you want to add or remove elements to/from an array, you have to create a new one). While elements can be added and removed ... Jul 24, 2016 · A sorting algorithm performs a lot of comparisons between pairs of sorted objects (pairs of Pair s in your case).
