// <NAME, ANDREW ID, SECTION>

// Do not modify the Hw8Television main class.  Make this code work
// by adding the appropriate classes with the appropriate methods as
// described by the test methods called by the main method.

// Note that you do not have to add any code to the test cases, though
// you do have to solve them with general-purpose solutions (and not just
// hard-code the example test cases!).

// Hint: to solve this incrementally, you may wish to comment out
// parts of the test code so the parts you have implemented will compile
// and can be tested as you go.
