@Entity
public class Question extends Model{

    @Required
    public String question; 
    @Required
    public String[] choices ;
    @ManyToOne
    public TestClass test;
    @Required
    public Integer trueChoice;

    public Question(TestClass test, Integer trueChoice, Choices[] choices, String question){
        this.test = test;
        choices = new Choices[4];
        this.trueChoice = trueChoice;
        this.question = question;
    }

}

Answer 1

If you look at the YAML documentation (section 2.1) or the Wikipedia page, they describe how lists are used. a list is described by using the dash symbol (-) for each item, on a new line. Please note the indentation.

For your example, you would have something like the following:

choices:
  - choice1
  - choice2
  - choice3
