Question

4) Write a Java program using Conditions: Write a program where it will ask user to enter a number and after that it will give you answer how many digits that number has.

Steps: 1) Create Scanner object and prompt user to enter the number and declare variable integer for input

2) Use if else condition with && condition where you will specify the digits of numbers by writing yourself the digit number that should display: Example(num<100 && num>=1), and so on

3) After using if else statement for any possibility in the end just declare that number is not between 1 and 99999

4) Output condition should look something like this:

OUTPUT EXAMPLE:

Enter a number:

56891

It’s a five digit number

Answer 1

Have a look at the below code. Its quite intutive to understand.

import java.util.*;

class Main {
  public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);

    System.out.println("Enter the number");

    int number = sc.nextInt();

    if (number>=1 && number<=9){
      System.out.println("It’s a one digit number");
    }
    else if(number>=10 && number<=99){

      System.out.println("It’s a two digit number");

    }

    else if(number>=100 && number<=999){

      System.out.println("It’s a three digit number");

    }

     else if(number>=1000 && number<=9999){

      System.out.println("It’s a four digit number");

    }

     else if(number>=10000 && number<=99999){

      System.out.println("It’s a five digit number");

    }

    // Like this you can ad as many conditions as per your requirement...
  }
}
