Write a function void change() with two string parameters. Interchange/swap the strings and print the strings before and after interchange.

 THE FOLLOWING PROGRAM SEGMENT SHOWS HOW TO SWAP THE STRINGS ENTERED:

class t

{

    void change(String s1, String s2)

    {

        String n1 = s1, n2 = s2;

         

        

        System.out.println("The Strings before interchange = ");

        System.out.println("String s1 = "+n1);

        System.out.println("String s2 = "+n2);

        String temp = "";

        temp = n1;

        n1 = n2;

        n2 = temp;

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

        System.out.println("The String s1 = "+n1);

        System.out.println("The String s2 = "+n2);

    }

    public static void main (String args[])

    {

        t obj = new t();

        obj.change("HAPPY", "GOODNESS");

    }

}

The above program CODE is compiled and is without any error.
