halfadder.java

基于ANdroid平台的高欢堂书籍的对应源代码 非常有用

package com.misoo.gx05;
public class HalfAdder {
    private int a,b, carry, sum;
	HalfAdder(){}
	public void set_digits(int d1, int d2)   {	a = d1;  b = d2; 	}
	public void run()      {	carry = a & b;   sum = a ^ b;	}
	public int get_carry(){  return carry;	}
	public int get_sum(){   return sum;	}
}
