Let’s learn multiply two numbers without using arithmetic operators in java.

## Multiply two numbers without using arithmetic operators in java

We can multiply two numbers without using arithmetic operators.

import java.util.Scanner; public class MultiplyWithoutArithmeticOperators { static int multiplyNumber(int num1, int num2) { int output = 0; boolean boolNegative = (num1 < 0 && num2 >= 0) || (num2 < 0 && num1 >= 0); boolean boolPositive = !boolNegative; num1 = Math.abs(num1); for(int a = 0; a < num1; a++) { if(boolNegative && num2 > 0 || boolPositive && num2 < 0) { output -= num2; } else { output += num2; } } return output; } public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.print("Please enter first number: "); int num1 = sc.nextInt(); System.out.print("Please enter second number: "); int num2 = sc.nextInt(); System.out.println("Multiplication of two numbers: " +multiplyNumber(num1, num2)); sc.close(); } }

**Output:**

Please enter first number: 8

Please enter second number: 5

Multiplication of two numbers: 40
