第六天做的作业的练习答案

package basic; public class Demo3 { public static void main(String[] args) { //第三方传值 int a = 13; int b = 7; System.out.println("a的值"+a+" "+"b的值"+b); int c = a; a =b; b = c; System.out.println("a的值"+a+" "+"b的值"+b); //第二种方法异或 a = 13; b = 7; System.out.println("a的值"+a+" "+"b的值"+b); a=a^b; b=a^b; a=a^b; System.out.println("a的值"+a+" "+"b的值"+b); //第三种方法加减法 a = 13; b = 7; System.out.println("a的值"+a+" "+"b的值"+b); a=a+b; b=a-b; a=a-b; System.out.println("a的值"+a+" "+"b的值"+b); } }
