# Java 程序：匯總數組的元素 > 原文： [https://beginnersbook.com/2014/01/java-program-to-sum-the-elements-of-an-array/](https://beginnersbook.com/2014/01/java-program-to-sum-the-elements-of-an-array/) 在本教程中，我們將看到**如何匯總數組**的所有元素。 計劃 1：沒有用戶互動 ```java /** * @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); } } ``` 輸出： ```java Sum of array elements is:160 ``` 程序 2：用戶輸入數組的元素 ```java /** * @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); } } ``` 輸出： ```java Enter the elements: 1 2 3 4 5 6 7 8 9 10 Sum of array elements is:55 ```
