Exclusive or operator simple logic operation a^=b

^ Is a bitwise XOR operation

a^=b Equivalent to a = a^{b, among} It's a bitwise exclusive or operation , the a And b XOR operation on the corresponding bit of , A fellow 0 Or both 1 when , The corresponding bit result is 0; Otherwise 1.
hypothesis ,a The value of is binary 1010,b The value of is binary 1100, that a^b = 0110

describe
Enter two positive integers a and b, Output the sum of these two positive integers , Bad , product , merchant , model （ if a>b The output a-b,a/b,a%b The value of... Is output in reverse b-a,b/a,b%a Value , Do not consider decimals , Please use int type ）
Input description ：
Two positive integers
Output description ：
Their and , Bad , product , merchant , model . Each value is separated by a space
Example 1

 public static void main(String[] args) {
        System.out.println(" Please enter two decimal places ");
        Scanner scanner = new Scanner(System.in);
        int a = scanner.nextInt();
        int b = scanner.nextInt();
        scanner.close();
        // The above code   Basic is the basic data input 

        // Here's your judgment   Default to  a>b When   By default, the data of the following program will be used （ skip if）  In line with business logic 
        // When he was less than b Enter the following if
       //EG:a=10 2 Of 3 Power +2 Of 1 The second party is =10  So his value is  1010
       // b=20 2 The fourth power of +2 To the power of  = 10100
        if (a < b) {
            //a=a^b a= 1010^10100= 1110 =30
            a ^= b;
            //b= b^a; a=30 b=20 20^30=10 b=10
            b ^= a;
            //a=a^b a=30 b=10 a=20 b=10  Equivalent position   It is equivalent to changing the value position 
            a ^= b;
        }
       // %d： Integer output   Convert the contents of his output to the shape output 
        System.out.printf("%d %d %d %d %d", a + b, a - b, a * b, a / b, a % b);
    }

The result of his output is ：

 Please enter two decimal places 
10
20
30 10 200 2 0

Another relatively simple method of operation ：

if(a>b){
        System.out.println((a+b)+" "+(a-b)+" "+(a*b)+" "+(a/b)+" "+(a%b));
    }else{
        System.out.println((a+b)+" "+(b-a)+" "+(a*b)+" "+(b/a)+" "+(b%a));
    }
}
