Answer Happy

Please answer in java, thank you.
Use Final Exam.java as your starting point Implement the five subroutines, as described in the comments. Each subroutine is worth 8 points. HINT: It might be easier to start at the bottom and work your way up.

import java.util.Arrays; public class FinalExam { // main() // // [2p] Creates an array of five random doubles between and 10. 1/ [2p] Prints the array to standard output (HINT: use Arrays.toString(). // [2p] Sorts the array using the selectionSort() function below. // [2] Prints the sorted array to standard output. // Erase this line and put your main() subroutine here. 1111 // selectionSort) // // [1p] input : an array of doubles "a". // [1] output: an array of doubles "a". // // [6] Uses the functions fromTo(), indexOfMax(), and swap() to execute a // Selection Sort, in which the largest element is repeatedly moved to 1/ the end of the array, and the largest index under consideration is // reduced by one. // // HINT: You may consult section 7.4.4 in our textbook, but do not simply // copy the code from that section. Your implementation of selectionsort // must call the functions fromTo(), indexOfMax(), and swap() to receive // points. // Erase this line and put your selectionSort() subroutine here. // fromTo // // [3p] input : two integers "m" and "n", and an array of doubles "a". // (1p] output: an array of doubles "b". // [4p] Gets an array that starts at a[m] and stops at a[n), and also // includes all of the elements in between (in their original order). // In other words, this function returns the input array "a", but only // from index "m" up to (and including) index "n". // // HINT: The length of the output array "b" is n - m + 1. // Erase this line and put your fromTo() subroutine here.

// indexOfMax) // 1/ [10] input : an array of doubles. 1/ [1p] output: an integer. // // [6p] Returns the INDEX of the maximal element of an array. // Erase this line and put your indexOfMax() subroutine here. // swap // [3p] input : two integers "m" and "n", and an array of doubles "a". // [10] output: an array of doubles "a". // // [4] Interchanges the elements a[m] and a[n), so that a[m] is where a[n] used to be, and a[n] is where a[m] used to be. // // HINT: You will need to define a temporary variable in order to // interchange the two elements of the array. // Erase this line and put your swap() subroutine here. }
