Write a program to input a string. Convert each alphabet into its opposite case. Print both the strings.

 THE FOLLOWING PROGRAM SEGMENT SHOWS HOW TO INPUT  A STRING AND CONVERT EACH OF THE STRING INTO ITS OPPOSITE CASE AND PRINT IT.

import java.util.*;

class U

{

    public static void main (String args[])

    {

        Scanner ob = new Scanner (System.in);

        System.out.println("Enter a String");

        String s = ob.nextLine();

        String st = "";

        for (int i = 0; i < s.length(); i++)

        {

            char ch = s.charAt(i); char c;

            if(ch >= 'A' && ch <= 'Z')

            

                ch += 32;

            

                else if(ch >= 'a' && ch <= 'z')

                

                  ch -= 32;

                  st = st+ch;

                

                

                

            }

            System.out.println("Output");

            System.out.println("Original String = "+s);

            System.out.println("Converted string = "+st);

            }

        }

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