Write a program to enter two strings s1 and s2 , and swap them. Print the strings before and after swap.

 THE FOLLOWING PROGRAM SEGMENT SHOWS HOW TO ENTER TWO STRINGS AND SWAP THEM .

import java.util.*;

class swapSTRINGS

{

    public static void main (String args[])

    {

        Scanner ob = new Scanner (System.in);

        System.out.println("Enter 2 strings");

        String s1 = ob.nextLine();

        String s2 = ob.nextLine();

       System.out.println("The strings before interchange are ");

       System.out.println("The String s1 = "+s1);

       System.out.println("The String s2 = "+s2);

        String temp = "";

        temp = s1;

        s1 = s2;

        s2 = temp;

        System.out.println("The strings after interchange are = ");

        System.out.println("The String s1 ="+s1);

        System.out.println("The String s2 = "+s2);

    }

    }

The strings before interchange =

The String s1=  askris

The String s2 =  blooger
