Add a method insertionSort to the class ArraySorter, that performs an insertion sort of an array. The algorithm is described in detail on wikipedia. for (index = 1; index < a.length; index++) insert value at index into the the appropriate place in the sorted subsection of the array, increasing the length of the sorted subsection by 1

Please add a method insertionSort to the class ArraySort and follow the algorium above. I will give the ArraySort below. Also please use IDE to finish this question. In the result, it should show 2 arrays with numbers, one is for before sorting, one is for after sorting.

here is the ArraySorter class

public class ArraySorter { /** Precondition: Every element in anArray has a value. Action: Sorts the array into ascending order. */ public static void selectionSort(int[] anArray) { for (int index = 0; index < anArray.length - 1; index++) { // Place the correct value in anArray[index] int indexOfNextSmallest = getIndexOfSmallest(index, anArray); interchange(index, indexOfNextSmallest, anArray); //Assertion:anArray[0] <= anArray[1]< =...<= anArray[index] //and these are the smallest of the original array elements. //The remaining positions contain the rest of the original //array elements. } } /** Returns the index of the smallest value in the portion of the array that begins at the element whose index is startIndex and ends at the last element. */ private static int getIndexOfSmallest(int startIndex, int[] a) { int min = a[startIndex]; int indexOfMin = startIndex; for (int index = startIndex + 1; index < a.length; index++) { if (a[index] < min) { min = a[index]; indexOfMin = index; //min is smallest of a[startIndex] through a[index] } } return indexOfMin; } /** Precondition: i and j are valid indices for the array a. Postcondition: Values of a[i] and a[j] have been interchanged. */ private static void interchange(int i, int j, int[] a) { int temp = a[i]; a[i] = a[j]; a[j] = temp; //original value of a[i] } }
