1. Create an array of 15 integers.
2. Populate it with values from the keyboard.
3. Let the array index represent the house number. The array value at a particular index represents the number of people living in the corresponding house.
Houses with odd numbers are located on one side of the street. Those with even numbers are on the other side. Find out which side of the street has more people living on it.
4. Display the following message: "Odd-numbered houses have more residents." or "Even-numbered houses have more residents."

Note:
The house at index 0 is considered even.

5. If the number of residents on each side of the street is the same, then output nothing.

Requirements:

The program must create an array of 15 integers.
The program should read numbers for the array from the keyboard.
The program should display "Odd-numbered houses have more residents." if the sum of odd array elements is greater than the sum of even ones.
The program should display "Even-numbered houses have more residents." if the sum of even array elements is greater than the sum of odd ones.
The program should not output text to the console if the number of residents on each side is the same.

//TRY this // You have to fill the rest including the if statements for odd and even int[] apt = new int[15]; int odd = 0; int even = 0; Scanner kb = new Scanner(System.in); for (int i = 0; i < apt.length; i++) { apt[i] = kb.nextInt(); } for (int i = 0; i < apt.length; i++) { if (i == 0 || i % 2 != 0) { odd += apt[i]; } else if (i % 2 == 0) { even+= apt[i]; }

It looks like this code is using the user entry as "house number" and then increasing even/odd by 1. The index number represents house number according to the task requirements and user input represents the number of people living at that house number. The code should be counting how many people live at odd numbered houses and how many live at even number houses. House number = Index # of people living at each = user input
