Java 实例 汇总数组的元素

在本教程中，我们将看到如何汇总数组的所有元素。

计划 1：没有用户互动

/** * @author: BeginnersBook.com * @description: Get sum of array elements */class SumOfArray{   public static void main(String args[]){      int[] array = {10, 20, 30, 40, 50, 10};      int sum = 0;      //Advanced for loop      for( int num : array) {          sum = sum+num;      }      System.out.println("Sum of array elements is:"+sum);   }}

输出：

Sum of array elements is:160

程序 2：用户输入数组的元素

/** * @author: BeginnersBook.com * @description: User would enter the 10 elements * and the program will store them into an array and  * will display the sum of them. */import java.util.Scanner;class SumDemo{   public static void main(String args[]){      Scanner scanner = new Scanner(System.in);      int[] array = new int[10];      int sum = 0;      System.out.println("Enter the elements:");      for (int i=0; i<10; i++)      {          array[i] = scanner.nextInt();      }      for( int num : array) {          sum = sum+num;      }      System.out.println("Sum of array elements is:"+sum);   }}

输出：

Enter the elements:12345678910Sum of array elements is:55
