计算数组元素的乘积。
- 创建一个空变量。(乘积)
- 将其初始化为 1。
- 循环遍历每个元素(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
