# Trivia Game

This is a beginning of a trivia game. Click the Q for a new question.

To Do:

1. Check to see if the answer is correct
2. Keep score
3. Make the questions an ArrayList rather than an array, so you can remove a question once it has been asked.

# Question.java

// instance variables - replace the example below with your own

/**
* Constructor for objects of class Question
*/

}

//shuffle 5 to 25 times

}
