阵列元素的 Java 程序乘法
查找阵列元素的乘积。
- 创建一个空变量。(乘积)
- 将其初始化为 1。
- 在一个循环中遍历每个元素(或从用户那里获取每个元素),将每个元素乘以乘积。
- 打印乘积。
示例
import java.util.Arrays; import java.util.Scanner; public class ProductOfArrayOfElements { public static void main(String args[]){ System.out.println("Enter the required size of the array :: "); Scanner s = new Scanner(System.in); int size = s.nextInt(); int myArray[] = new int [size]; int product = 1; System.out.println("Enter the elements of the array one by one "); for(int i=0; i<size; i++){ myArray[i] = s.nextInt(); product = product * myArray[i]; } System.out.println("Elements of the array are: "+Arrays.toString(myArray)); System.out.println("Sum of the elements of the array ::"+product); } }
输出
Enter the required size of the array: 5 Enter the elements of the array one by one 11 65 22 18 47 Elements of the array are: [11, 65, 22, 18, 47] Sum of the elements of the array:13307580
