Q1 Modify the above code to do the following. Create a boolean value, with the identifier
      Sunday. The code should print out to console, 'Rest' if the condition of the if...else
      statement is true and 'Work' if it is false.  // there's an example like this in the note

Considering  the switch example in the code above . . .

Q2 What happens (in example 2) if the condition in the for loop of the switch above  is
      changed to i > -1? What is going on here?

Q3 Comment out the 'break' keywords in the above switch. What happens? Why?

Q4 Adapt the above switch code to print out a count down for a rocket take off.
   i.e. ten, nine eight ... blastoff!  Make the thread sleep for 1000 milliseconds
   between counts.

Q5 Write a for loop that loops 10 times.  Put in a print statement that prints the index i
      at each loop. Includen an 'if' statement whose 'else' part causes the the 5th iteration's
      index not to be printed out.  (Printing continues on the 6th iteration)

Q6 Copy the loop you created in Q5 and change it so it stops printing after the 5th iteration.

Q7 Put the int value 99 into an instance of Integer. Look in the JDK API, in a text or in your
      notes to get a method to return it to an identifier with type double. Print this value to screen.
