4. Implement the Bird class using BlueJ. The Bird class has the following fields: name (String): Stores the name of the bird size (double): Stores the size of the bird flying speed (int): Stores the flying speed of the bird weight (double): Stores the weight of the bird current elevation (int): Stores the current elevation of the bird count: Stores the number of birds created GRAVITY: A constant with a value of 9.8. The class should have the following constructor and methods: .A constructor that accepts the following arguments and assigns them to the appropriate fields: name, size, flying speed, and weight. Constructor should assign 0 to current elevation and increment the count field by 1. Get methods for all the fields Set methods for the name field. . . Eat method will accept amount of food as parameter and will update the size and weight fields using the following formulae: size = size+ amount of food *2 100 weight = weight + amount of food *5 100 . Fly Up method will update the current elevation and weight fields using the following formulae: Current Elevation = Current Elevation + Flying Speed weight *GRAVITY Weight = Weight -3

Fly Down method will update the current elevation and weight fields using the following formulac: Current Elevation = Current Elevation- _Flying Speed weight . GRAVITY Weight = Weight -1 Once you have written the Bird class, write a separate java class called BirdDemo (with main method) that creates three bird objects to hold the following data: Name Size Flying Speed Weight Blue J I 10 100 3.8 Blue J 2 12 95 3.5 Blue] 3 15 125 3 The program should store the data in three objects of bird type and than: Display total number of birds Display information about Blue J I Feed 10 grams of food to the Blue J I Display information about Blue J I Display information about Blue J 2 Make Blue J 2 fly up Display information about Blue J 2 Display information about Blue J 3 Make Blue J 3 fly down Display information about Blue J 3 Do not forget to include the JavaDoc and Make sure that you can compile and run your program. What to Hand in I. Question 1, 2 and 3 can be done using Microsoft Office, Open Office, or plain old text editor. Submit the document using Moodle. 2. Question 4 must be done using BlueJ. Zip your project folder and submit using Moodle.
