Question

public class Main
{
public static void main(String [] args)
{
int [] array1 = {5, 8, 34, 7, 2, 46, 53, 12, 24, 65};
int numElements = 10;

System.out.println("Part 1");
// Part 1
// Enter the statement to print the numbers in index 5 and index 8
// put a space in between the two numbers and a new line at the end

// Enter the statement to print the numbers 8 and 53 from the array above
// put a space in betwaeen the two numbers and a new line at the end.

// Enter the statement to change the number 2 in the array to be 12
// then write the statement to print out that number in the array
// and a new line at the end

System.out.println("Part 2");
// Part 2
// Write the loop to print out all of the numbers in the array
// Use the variables declared above (you might have to declare
// another variable) Put a space between each number

System.out.println("\nPart 3");
// Part 3
// Write the loop to print out all of the EVEN numbers in the array
// Use the variables declared above (you might have to declare
// another variable) Put a space between each number.   

System.out.println("\nPart 4");
// Part 4
// Write a method called computeTotal that has the array
// and the number of elements passed into it. It will return
// the total of all of the numbers in the array (it will be
// below the main method)
int total;
// Call the function you just wrote and store the answer
// in the variable total declared above

// This will print the total out
System.out.println(total);
