Write a program IntWrapper that uses the constants and methods of the Integer class to perform the following tasks. Be sure to clearly label your output and test your code for each task before proceeding.

1. Prompt for and read in an integer, then print the binary, octal and hexadecimal representations of that integer.
2. Print the maximum and minimum possible Java integer values. Use the constants in the Integer class that hold these values -- don't type in the numbers themselves. Note that these constants are static (see the description on page 140 and the signature on page 819).
3. Prompt the user to enter two decimal integers, one per line. Use the next method of the Scanner class to read each of them in. (The next method returns a String so you need to store the values read in String variables, which may seem strange.) Now convert the strings to ints (use the appropriate method of the Integer class to do this), add them together, and print the sum.
