We want to ask questions such as

In which country was the inventor of Java born?
1. Australia
2. Canada
3. Denmark
4. United States

Provide these methods of a class ChoiceQuestion:

• a constructor
• a method addChoice to add a choice, and to indicate whether it is the correct one
• a method format that formats the question for printing
• a method checkAnswer that checks whether a student answer is correct.

It should be possible to call

ChoiceQuestion q = . . .;
q.addChoice("Australia", false);
q.addChoice("Canada", true);
q.addChoice("Denmark", false);
q.addChoice("United States", false);

Store the choices in the provided String[] array. No lists! Note that you'll have to deal with the fact that the answers come one at a time. Also, you'll want to record the correct answer somehow.
