        double d2 = scan.nextDouble();
                   scan.nextLine();
        String s2 = scan.nextLine();
        
        /* Read and save an integer, double, and String to your variables.*/
        // Note: If you have trouble reading the entire String, please go back and review the Tutorial closely.
        
        /* Print the sum of both integer variables on a new line. */
        System.out.println(i+j);//4+12 = 16
        /* Print the sum of the double variables on a new line. */
        System.out.println(d+d2);//4.0+4.0=8.0
        /* Concatenate and print the String variables on a new line; 
            the 's' variable above should be printed first. */
        System.out.println(s+s2);//HackerRank 
        scan.close();
