Answer:

import java.util.Scanner;

import java.util.Random;

public class Solution

{

public static void indexEven(int[] randomNumbers)

{

System.out.print("Even index elements are: ");

for (int i = 0; i < randomNumbers.length; i++)

{

if (i % 2 == 0)

{

System.out.print(randomNumbers[i] + " ");

}

}

System.out.println();

}

public static void evenelement(int[] randomNumbers)

{

System.out.print("Every even element: ");

for (int i = 0; i < randomNumbers.length; i++)

{

if (randomNumbers[i] % 2 == 0)

{

System.out.print(randomNumbers[i] + " ");

}

}

System.out.println();

}

public static void reverseOrder(int[] randomNumbers)

{

System.out.print("All elements in reverse order: ");

for (int i = randomNumbers.length - 1; i >= 0; i--)

{

System.out.print(randomNumbers[i] + " ");

}

System.out.println();

}

public static void firstLast(int[] randomNumbers)

{

System.out.print("First and last elements are: ");

System.out.print(randomNumbers[0] + " " + randomNumbers[randomNumbers.length - 1]);

System.out.println();

}

public static void main(String[] args)

{

// create instance of Random class

Random rand = new Random();

System.out.print("Array: ");

int[] randomNumbers = new int[10];

for (int i = 0; i < randomNumbers.length; i++)

{

randomNumbers[i] = rand.nextInt(100);

System.out.print(randomNumbers[i] + " ");

}

System.out.println();

indexEven(randomNumbers);

evenelement(randomNumbers);

reverseOrder(randomNumbers);

firstLast(randomNumbers);

}

}
