（java版）数组求和

通过简单的数组求和，了解动态数组的构建

package com.ty.java;

import java.util.Scanner;

public class word {
public static void main(String[] args) {
    int[] a = null;
    a = new int[10];                  //构建动态数组
    int sum = 0;    
    Scanner sc = new Scanner(System.in);       //构建输入数组的属性
    for (int i = 0; i < a.length; i++) {
        a[i] = sc.nextInt();
        sum += a[i];
    }
    System.out.println("和 = " + sum);
 }
}

代码运行如下：

com.ty.java.word
12 45 32 69 21 31 56 68 99 50
和 = 483
