You can multiply two numbers 'm' and 'n' by repeated addition method.
For example, 5 * 3 = 15 can be performed by adding 5 three times ⇒ 5 + 5 + 5 = 15

Similarly, successive subtraction of two numbers produces 'Quotient' and 'Remainder' when a number 'a' is divided by 'b' (a>b).
For example, 5/2 ⇒ Quotient = 2 and Remainder = 1
Follow steps shown below:

Process	Result	Counter
5 - 2	3	1
3 - 2	1	2

Sample Output: The last counter value represents 'Quotient' ⇒ 2
The last result value represents 'Remainder' ⇒ 1

Write a program to accept two numbers. Perform multiplication and division of the numbers as per the process shown above by using switch case statement.

import java.util.Scanner;

public class KboatArithmetic
{
    public void computeResult() {

        Scanner in = new Scanner(System.in);
        System.out.print("Enter first number: ");
        int a = in.nextInt();
        System.out.print("Enter second number: ");
        int b = in.nextInt();
        System.out.println("1. Multiplication");
        System.out.println("2. Division");
        System.out.print("Enter your choice: ");
        int ch = in.nextInt();
        
        switch (ch) {
            case 1:
            int rMul = 0;
            for (int i = 1; i <= b; i++) {
                rMul += a;
            }
            System.out.println("Multiplication result = " + rMul);
            break;
            
            case 2:
            int count = 0, t = a;
            while (t > b) {
                t -= b;
                count++;
            }
            System.out.println("Divison Result");
            System.out.println("Quotient = " + count);
            System.out.println("Remainder = " + t);
            break;
            
            default:
            System.out.println("Incorrect Choice");
            break;
        }
    }

}
