A zoo is expecting new-born giant pandas soon, as one of their pandas is having young. New-born giant pandas are just around 100g but, if they are healthy, they gain weight very rapidly after birth. The zoo plans to monitor the baby pandas weight carefully for the first months of their lives. An application is being created to help the zoo monitor the pandas weight gain. One of the classes in this application is called Panda. i. The class Panda has a property called weightatbirth that stores the weight (in kg) of the panda at birth. Show how this property would be declared in Java. double weightatbirth; [Accept also float. Do not accept int, byte etc] ii. The class Panda also has a property called ageindays that stores the age of a panda in days. Show how this property would be declared in Java. int ageindays; [Accept all integer data types] ii. Write Java code to create an object of class Panda called panda1. Panda panda1 = new Panda(); iii. Method weighin() asks the user to enter the age and weight of a given panda and then outputs the weight gained to date. Write method weighin(). Assume that classes needed for this method, if any, are already imported. Relevant objects of this/these classes (if any) are to be declared in method weighin() 1 mark for correct calculation 1 mark for correct output 1 mark for input from keyboard 1 mark for overall functionality iv. Write Java code to call method weighin() for your object panda1. panda1.weighin(); [1 for partially correct answer] v. After thirty days the panda should weigh around 2kg. Write method isprogressok() that returns false if a panda s weight is less than 1.8kg and otherwise returns true. 1 mark for correct method declaration 1 mark for implementation of decision structure 1 mark for correct decision 1 mark for return of correct value 1 mark for overall functionality 7 [4] [5]
