Selection Sort in Java

public class SelectionSort {

public static void sort(int[] arr) {
    // Iterate over the entire array, except the last element (0...n-1).
    for(int i = 0; i < arr.length - 1; i++) {

        // Iterate the remaining array (i...n)
        for(int j = i + 1; j < arr.length; j++) {
            // If j is less than the minimum, update the min index.

            }
