Use Animal.java, GuinnessBook.java, and animalList.txt.

public class Animal { private String name; private int topSpeed; //create the getters and setters for the instance variables //there is a shortcut by hovering over the variable names // For the setter associated with topSpeed make sure the values are between 0 and 70 // Print "Invalid Speed" if it is not within these values and leave // the speed unchanged. //create a constructor that takes in a String for the name and an int for the topSpeed //use only the setters initialize the instance variables //create an equals(Object other) method that returns True if the two Animal objects have //top speeds that are within 2 mph of each other // Create a toString method // Formatting of the returned String should follow this example: // Name: elephant Top Speed: 25 }

Complete the implementation of Animal.java, by adding the following methods:

1. Getters and setters for name and topSpeed. Print an error if topSpeed is over 70 or below 0 and leave the speed alone.

2. A constructor that takes in a String for the name and an int for the topSpeed. Use the setters to set the instance variables.

3. a toString() method that returns a string with that animal's information. EX: Name: elephant Top Speed: 25

4. an equals(Object other) method that returns True if two animals have the same speed within 2mph, and False otherwise (recall that equals takes in an instance of Object rather than Animal, in order to override the default implementation of equals).

When implementing constructors, getters/setters, toString or equals methods you can use Eclipse to help you write those methods - under the "Source" tab of Eclipse there are options for generating stubs for those methods. In GuinnessBook.java:

1. Complete the code for the constructor. You just need to add code that adds the animals to the landAnimals arrayList.

2. The toString() method. This can make use of Animal's toString()method. It should return a string representation of all the elements in the arrayList. EX:

Name: giraffe Top Speed: 32

Name: pronghorn Top Speed: 61

Name: reindeer Top Speed: 32

Test your code in the main method.

Follow the instructions in main and testGuinnessBook
