AddLogical.java

public class AddLogical {
    public static void main(String[] args) {
        int a = 231;
        int b = 35;
        System.out.printf("%d + %d = %d%n", a, b, a + b);
        while(b != 0){
            int c = a ^ b;
            b = (a & b) << 1;
            a = c;
        }
        System.out.println(a);
                
    }
}

231 + 35 = 266
266
