Question

Task 4: Integer and Floating Point Division

Open Division.java and write code to solve the following problem:

1. prompts for and reads in an integer (on the same line)

2. Outputs:

i) the value of the number divided by 100 as a floating point value

ii) the remainder when the number is divided by 100

iii) the number of times 100 divides the integer

iv) outputs the digits of the integer in reverse order; i.e., each digit must be extracted

arithmetically.

You may assume the number is less than 10000.

Here are some examples of how your program should behave (user input is in bold):

Example 1

Enter an integer: 1534

15.34

34

15

4351

Example 2

Enter an integer: 403

4.03

34

304

Example 3

Enter an integer: 4

0.04

404

Hint: 1534 % 10 has a value of 4 and 1534 / 10 has a value of 153.

import java.util.Scanner;

public class Division {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        // declare any variables here

        // Output the values here.
    }
}

Answer 1

Outputs of Example 2 and 3 are wrong as they do not follow your given output guidelines.

import java.util.Scanner;

public class Division {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        System.out.print("Enter an Integer: ");

        int n = sc.nextInt();

        System.out.println((float)n/100);

        System.out.println(n%100);

        System.out.println(n/100);

        System.out.println(reverseInt(n));

        sc.close();

    }

    public static int reverseInt(int n) {

        int rev = 0;

        while(n > 0) {

            rev = rev*10 + n%10;

            n = n/10;

        }

        return rev;

    }

}

Output:

1-

Enter an Integer: 1534
15.34
34
15
4351

2-

Enter an Integer: 403
4.03
3
4
304

3-

Enter an Integer: 3
0.03
