The following variables/constants should be declared in your program:

Step 6: The Logic in Your Program (Outside of the Main Method)

Note: All of the following methods should be declared outside the main method in order for your program to work correctly. The first method is shown below:

public static void printArray(int[] list)
{
int i;

System.out.println(" The array has these numbers:");

for (i = 0;i < list.length; i++)
{
System.out.println(list[i]);
}

} // end method printArray

In all of your methods, you should use the list.length when applicable, as it contains valuable information.

There are four more methods, for which the method headers are shown below:

public static int getTotalSum(int[] list) - this method will sum up all of the element's values in the array list and then return this value

public static int getTotalEvenNumbers(int[] list) - this method will only count how many even numbers there are in the array list and then return this value

public static int getTotalOddNumbers(int[] list) - this method will only count how many odd numbers there are in the array list and then return this value

public static void updateEvenNumbers(int[] list) - this method will only update those numbers that are even in the array list; so for example if an element at index 5 is an even number, multiply that number by 3 to update it.
