Java Program to Separate the Individual Digit of a 3-Digit Number!

PRINTING THE INDIVIDUAL DIGITS OF A NUMBER

AIM:  To write a program to print the individual digits of a 3-digit number.

ALGORITHM:

1. Declare variables n and r of type int with in method main()
2. Obtain the input for n through the command line argument args[], a string array.
3. Convert the value of args[0] – the input, into integer and store it in n.
4. Apply / (division operator) and find n/100 to separate the left most digit of n and print it
5. Apply both / and % operators to separate the middle digit like this: (n/10)%10 and print it
6. Apply only % (modulus operator) on n (n%10) to get the least significant and print it.

PROGRAM:

public class SeparatingDigits

{

    public static void main(String[] args) {

        int n,r;

        n = Integer.parseInt(args[0]);

        System.out.println("The Given Number is : " + n);

       

        System.out.println("The Individual Digits are : ");

        r = n / 100;     /*Find the First digit - which is in Hundre's place*/

        System.out.println(r);

        r = (n/10)%10;       /*Find the Second digit - which is in the Hundred's place)*/

        System.out.println(r);

        r = n%10;       /*Find the Right Most digit - which is in the One's place)*/

        System.out.println(r);

    }

}
