Can any one tell me how to add two numbers using bitwise operators only.
After spending so much time on googling,i found the below java code.But is
is confusing.
<[email protected]>public class AddTwoNumbers {
private static int myAdd(int a, int b)
{
int carry = a & b;
int result = a ^ b;
while(carry != 0)
{
int shiftedcarry = carry << 1;
carry = result & shiftedcarry;
result ^= shiftedcarry;
}
return result;
}
public static void main(String[] args){
System.out.println(myAdd(4, 5));
}
}
Please explain it.
