Product of digits of a number in java
In this article you can learn how to write a program to find out the product of digits of a number in java by writing code in mobile phone.
Yes I always use my android phone (java N-IDE app) to write code for all programs.
Approach:-1 "find product of digits of a number in java using while loop"
public class usingWhileLoop {
public static void main(String[] args){
int num = 2316;
int product = 1;
while(num != 0)
{
int lastDigit = num % 10;
product = product * lastDigit;
num = num / 10;
}
System.out.println("The product is: "+product);
}
} Here our job is to find the digits one by one and multiply it to a product variable individually.
By using modulus operator(%), first I am fetching the last digit of the number and multiplying it to product variable (which is initially created).
Now we have to remove the last digit, we can do by simply dividing the number with 10.
This loop will go upto the number > 0 or number not equal to 0 (num != 0).
After multiplying first digits, the loop will terminate and finally the value of product of digits will be stored in the product variable.
