Java 交换两个变量值

import java.util.Scanner;

public class myClass {

 public static void main(String[] args) {

  // TODO 自动生成的方法存根

  @SuppressWarnings("resource")

  Scanner scan = new Scanner(System.in);

  System.out.println("Please input value of A : ");

  long A = scan.nextLong();

  System.out.println("Please input value of B : ");

  long B = scan.nextLong();

  System.out.println("A = " + A + "\t B = " + B);

  System.out.println("exchange result: ");

  A = A ^ B;

  B = B ^ A ;

  A = A ^ B ;

  System.out.println("A = " + A + "\t B = "+ B);

 

 }

}
