Question

Exercise #3: Design and implement a program (name it ArrayMethods), that defines 4 methods as follows:

 

int arrayMax(int[] arr) returns the maximum value in the an array

int arrayMin(int[] arr) returns the minimum value in an array

void arraySquared(int[] arr) changes every value in the array to its square (value²)

void arrayReverse(int[] arr) reverses the array (for example: array storing 7   8   9  becomes 9   8   7 )

 

The program main method creates a single-dimensional array of length 5 elements and initialize it with random integers between 1 and 100. The program displays the original array, then calls each of the above methods and displays their results as shown below. Document your code and organized your output following these sample runs.

 

Sample run 1:

 

Original array:  3, 5, 2, 6, 1

Max value:       6

Min value:       1

Squared array:   9, 25, 4, 36, 1

Reversed array:  1, 36, 4, 25, 9

 

Sample run 2:

 

Original array:  3, 2, 3, 7, 2

Max value:       7

Min value:       2

Squared array:   9, 4, 9, 49, 4

Reversed array:  4, 49, 9, 4, 9

 

Sample run 3:

 

Original array:  2, 2, 2, 2, 2

Max value:       2

Min value:       2

Squared array:   4, 4, 4, 4, 4

Reversed array:  4, 4, 4, 4, 4
