输入任意5个整数,输出它们的和。

import java.util.*;

public class Demo {
    public static void main(String[] args) {
        int intArray[] = new int[5]; //定义数组,并分配内存
        long total = 0;
        int len = intArray.length;   //数组的长度

        System.out.println("请输入" + len + "个整数,以空格为分隔:");
        Scanner sc = new Scanner(System.in);

        for (int i = 0; i < len; i++) {
            intArray[i] = sc.nextInt();
        }  //for循环遍历数组

        for (int i = 0; i < len; i++) {
            total += intArray[i];

        }
        System.out.println("所有数组元素的和为: " + total);
        sc.close();
    }

}
