Question

JAVA: Write a simple program that takes as input 2 16-bit strings, X and Y. Compute and and display the bitwise AND, bitwise OR, and bitwise XOR of the two strings.

Answer 1

import java.util.Scanner;

public class Bitwise {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter first 16-bit number: ");
        String X = in.next();
        System.out.print("Enter second 16-bit number: ");
        String Y = in.next();
        String xor="", or="", and="";
        char c1,c2;
        for(int i = 0; i < X.length(); i++) {
            c1 = X.charAt(i);
            c2 = Y.charAt(i);
            if(c1 == '0' || c2 == '0') {
                and += "0";
            } else {
                and += "1";
            }
            if(c1 == '0' && c2 == '0') {
                or += "0";
            } else {
                or += "1";
            }
            if((c1 == '0' && c2 == '1') || (c1 == '1' && c2 == '0')) {
                xor += "1";
            } else {
                xor += "0";
            }
        }
        System.out.println("AND = " + and);
        System.out.println("OR = " + or);
        System.out.println("XOR = " + xor);
    }
