Swapping in java

            Today we are learning about how to  swapping two number using java

1.I put the value of a in temp;
    temp=a;
2.now a is empty so i put the value of b on a;
    a=b;
3.now a is full with the value of b;
4.and b is empty so i put the value of temp in b
5.first we have three container temp, a,b;

package com.ritesh;

import java.util.Scanner;

public class swapping {
    public static void main(String[] args) {

        Scanner sc=new Scanner(System.in);
        System.out.println("Enter the value for a");
        byte a= sc.nextByte();
        System.out.println("Enter the value for b");
        byte b= sc.nextByte();
        System.out.println("The value of a before swapping is "+a);
        System.out.println("The value of b before swapping is "+b);
        byte temp;
        //first we have three container temp, a,b;
        //I put the value of a in temp;
        temp=a;
        //now  a is empty so i put the value of b on a;
        a=b;
        //now a is full with the value of b;
        // and b is empty so i put the value of temp in b
        b= temp;
        System.out.println();
        System.out.println("The value of a after swapping is "+a);
        System.out.println("The value of b after swapping is "+b);
        //we successfully change the value of a and b in each other.
    }
