Java: Add two numbers without using any arithmetic operators
Java Basic: Exercise-111 with Solution
Write a Java program to add two numbers without arithmetic operators.
Given x = 10 and y = 12; result = 22
Sample Solution:
Java Code:
import java.util.Scanner;
public class Example111 {
public static void main(String[] arg) {
int x, y; // Declare two integer variables, 'x' and 'y'
Scanner in = new Scanner(System.in); // Create a Scanner object for user input
System.out.print("Input first number: "); // Prompt the user to input the first number
x = in.nextInt(); // Read and store the first number from the user
System.out.print("Input second number: "); // Prompt the user to input the second number
y = in.nextInt(); // Read and store the second number from the user
while (y != 0) {
int carry = x & y; // Calculate the carry by bitwise AND operation between x and y
x = x ^ y; // Calculate the sum without considering the carry by bitwise XOR operation
y = carry << 1; // Calculate the carry for the next iteration by shifting it left by one position
}
System.out.print("Sum: " + x); // Print the sum of the two numbers
System.out.print("\n"); // Print a new line
}
}
Sample Output:
Input first number: 10 Input second number: 12 Sum: 22
