Exercise: Array Statistics with Methods

Write a console program that uses methods to:

create an int array of length 4
fill that array with random numbers from 1 to 8 inclusive
print the array exactly as shown below (no trailing comma)
print the biggest value in the array
print how many even numbers there are in the array (even means divisible by two without a remainder)
print the array in reverse.

Your program output should look like this:

Array: 4, 8, 2, 1
Biggest number: 8
Product: 64
Amount of even numbers: 3
Reversed array: 1, 2, 8, 4

Write these methods to accomplish the tasks:

createRandomNumbers - creates an array of random integers
toString - converts an integer array to a string
getBiggestNumber - gets the biggest integer from an integer array
getProduct - returns a BigDecimal by multiplying the numbers in an integer array
countEvenNumbers - gets the amount of even numbers in an integer array
reverseArray - returns a new array with the numbers of the input array in reverse order

Your main method can look like this:

int randNrsLength = 4;
int minIncl = 1;
int maxIncl = 8;

int[] randNrs = createRandomNumbers(randNrsLength, minIncl, maxIncl);

int biggestNr = getBiggestNumber(randNrs);
BigDecimal product = getProduct(randNrs);
int evenNrCount = countEvenNumbers(randNrs);
int[] reversed = reverseArray(randNrs);

System.out.println("Array: " + toString(randNrs));
System.out.println("Biggest number: " + biggestNr);
System.out.println("Product: " + product);
System.out.println("Amount of even numbers: " + evenNrCount);
System.out.println("Reversed array: " + toString(reversed));
