        System.out.println("Enter character in upper case :-->");
        char upper = sc.next().charAt(0);

        int ascii = upper + 32;
        System.out.println("Lower case of "+upper+" is : "+(char)ascii);

        // convert in Upper case
        System.out.println("Enter character in lower case :-->");
        char lower = sc.next().charAt(0);

        ascii = lower - 32;

        System.out.println("Upper case of "+lower+" is : "+(char)ascii);
