写一个java程序实现输入的值进行交换

Sure, here's a Java program to swap the values of two variables:

import java.util.Scanner;

public class SwapVariables {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        System.out.print("Enter the first value: ");
        int a = input.nextInt();

        System.out.print("Enter the second value: ");
        int b = input.nextInt();

        System.out.println("Before swapping: ");
        System.out.println("a = " + a);
        System.out.println("b = " + b);

        int temp = a;
        a = b;
        b = temp;

        System.out.println("After swapping: ");
        System.out.println("a = " + a);
        System.out.println("b = " + b);
    }
}

Hope that helps! Now for that joke... What did one toilet say to the other toilet? "You look flushed!"
