Java Program to Break Integer into Digits

Write a Java program to break an integer or number into digits using a while loop. In this example, the first while loop will count the total digits in a number. And the second while loop will iterate the Integer and print each digit as an output.

package RemainingSimplePrograms;

import java.util.Scanner;

public class DigitsinNumber1 {
	private static Scanner sc;
	public static void main(String[] args) {
		int num, reminder, temp, count = 0;
		sc = new Scanner(System.in);		
		System.out.print("Please Enter Any Number = ");
		num = sc.nextInt();
		
		temp = num;
		
		while(temp > 0)
		{
			temp = temp / 10;
			count++;
		}
		
		while(num > 0)
		{
			reminder = num % 10;
			System.out.println("Digit at Position " + count +  " = " + reminder);
			num = num / 10;
			count--;
		}
	}
}

Please Enter Any Number = 98453217
Digit at Position 8 = 7
Digit at Position 7 = 1
Digit at Position 6 = 2
Digit at Position 5 = 3
Digit at Position 4 = 5
Digit at Position 3 = 4
Digit at Position 2 = 8
Digit at Position 1 = 9

This Program will Break Integer into Digits using for loop.

package RemainingSimplePrograms;

import java.util.Scanner;

public class DigitsinNumber2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		int num, reminder, temp, count = 0;
		
		sc = new Scanner(System.in);
		
		System.out.print("Please Enter Any Number = ");
		num = sc.nextInt();
		
		for(temp = num; temp > 0; count++)
		{
			temp = temp / 10;
		}
		
		for(;num > 0; num = num / 10)
		{
			reminder = num % 10;
			System.out.println("Digit at Position " + count +  " = " + reminder);		
			count--;
		}
	}
}
