数组 求偶数

import java.util.Scanner;
public class Demo3{
    public static void main(String[] args) {
        int[] array = new int[5];
        Scanner scan = new Scanner(System.in);

            array[i] = scan.nextInt();

                sum += array[i];

        }

        System.out.println(sum);
        //定义10个元素的整数数组，键盘输入，求所有偶数下标的元素和
