Problem of the Day

Problem:

Consider the following class declaration, which describes a solid polygon that can be "rolled" to get a random result for playing games of chance.

public class Die
{
    private int result;
    private int sides;

    public Die()
    {
        sides = 6;
        roll();
        result = getResult();
    }
    
    public Die(int sides)
    {
        this.sides = sides;
        roll();
        result = getResult();
    }

    public void roll()
    {
        result = (int) (Math.random() * sides + 1);
    }
    
    public int getResult()
    {
        return result;
    }
}

Which of these are considered accessor methods?

public Die()
public Die(int sides)
public void roll()
public int getResult()

I only
I and II only
III only
IV only
III and IV only

Show solution:

The correct answer is d. An accessor method gets information from the object and returns it as a result. Because accessor methods often have the word "get" as part of their method name, they are sometimes referred to colloquially as "getters."
