I know I solved this one a bit differently than the "main solution" but I think this should work. However I'm getting an invalid method declaration. anyone know why?
package com.codegym.task.task07.task0706;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
/*
Streets and houses
*/
public class Solution {
public static void main(String[] args) throws Exception {
//write your code here
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
int[] array = new int[15];
for (int i = 0; i<array.length;i++)
array[i] = Integer.parseInt(reader.readLine());
int[] arrayeven = new int[8];
for (int i = 0;i <15;i+=2) {
int j = 0;
arrayeven[j] = array[i];
j++;
}
int[] arrayodd = new int[7];
for (int i = 1;i <15;i+=2) {
int j = 0;
arrayodd[j-1] = array[i];
j++;
}
if (sum(arrayeven)>sum(arrayodd))
System.out.println("Even-numbered houses have more residents.");
else
System.out.println("Odd-numbered houses have more residents.");
}
public static sum(int[] array) {
int sum = 0;
for (int i =0; i<array.length;i++) {
sum += array[i];
}
return sum;
}
}
