Write code in Java

Objective:

Use an abstract class to create a class hierarchy.

Use an interface to create another class hierarchy.

Instructions

1. Create an abstract class AbstractDieRoller:

public abstract class AbstractDieRoller { public int rollDie(int sides) {return ThreadLocalRandom.current.nextInt(1, sides + 1); } } Now extend the AbstractDieRoller to create the D6DieRoller class, and the D20DieRoller class. The D6DieRoller class will have a rollDie() method that returns a random number as in the range of 1-6. (The lowest number possible is 1, and the max number possible is 6.) Likewise, the D20DieRollerClass will have a rollDie() method that returns a random number in the ranger 1-20.

Now, in the Assessment class (which will have the main method),

- Create a D6DieRoller object and call its rollDie() method 6 times.

- Print out each die roll.

- Create a D20DieRoller object, and call its dieRoller() method 10 times, printing out each

random number.

2. Now to use an interface:

public interface PickBestOf2RollsChooseable { int getHighestOf2Rolls(); // roll the die twice, return the highest of the 2 results } Create a D6ReRoller class and a D20ReRoller class. Here is how to declare the D6ReRoller class:

public class D6ReRoller extends D6DieRoller implements PickBestOf2RollsChooseable {....}

Now, in the Assessment class (which will have the main method),

• create a D6ReRoller object and call its getHighestOf2Rolls() method 6 times.
• Print out each die roll.
• Create a D20ReRoller object, and call its getHighestOf2Rolls () method 10 times, printing out each random number.
