Question

I can't solve this for the life of me. Can anyone help?? Entry-level java

----------- Assignment below ------------

Create a simple trivia game for 2 players. The program will work like this:

Starting with player 1, each player gets a turn at answering 5 trivia questions.There are 10 questions, 5 for each player. When a question is displayed, four possible answers are also displayed. Only one of the answers is correct, and if the player selects the correct answer, he or she earns a point.

After answers have been selected for all of the questions, the program displays the number of points earned by each player and declares the player with the highest number of points the winner.

Design a Question class to hold the data for a trivia question. The Question class should have String fields for the following data:

A trivia question

Possibe Answer 1

Possible Answer 2

Possible Answer 3

Possible Answer 4

The number of the correct answer (1,2, 3, or 4)

The Question class should have appropriate constructor(s), accessors, and mutator methods. The program should create an ArrayList of 10 Question objects, one for each trivia question. Make up your own trivia questions on the subject of your choice.
