CSGE601021 Programming Foundations 2 @ Faculty of Computer Science Universitas Indonesia, Term 2 2017/2018
This document contains the description and general information required for completing the second assignment of Programming Foundations 2 course. The assignment is about creating a program for organising animals into their cages.
This assignment covers programming topics as follows:
- Object-oriented programming in Java
- Contiguous data containers such as array, multidimensional array, and
ArrayList
This assignment is published on Friday, March 16 2018. The due date for pushing latest commit for this assignment is on Friday, April 6 2018. Please refer to Submission section to see the actual due date and time.
You are a programmer who are assigned at Javari Park. As you may know, Javari Park has welcomed a train full of animals, not only a cat. They were hamster, lion, parrot, and eagle. Each animal has its own characteristic. One of your task is categorising the characteristics in the form of classes.
Generally, each registered animal has name, body length, and information about its cage. For every type of animals, you must keep the information of the number of registered animals, including their specifications. These informations were owned by the classes of animals. Their specification would be listed below.
Cats are friendly to human that everybody can visit their cages in Javari Park. Their fur must be brushed to clean it from fleas. They love it so much that they cutely make a voice of “Nyaaan...”. Besides, when they were cuddled by visitors, they also make voices such as: “Miaaaw..”, ”Purrr..“, “Mwaw!”, and “Mraaawr!”. Nobody know’s what sound they will make each time they are cuddled.
The next animal is Hamsters. They are rodents that could gnaw. Each time they gnaw, they will produce noise that sounds like "Ngkkrit.. Ngkkrrriiit". They can also run inside the hamster wheel and you will hear sound like "Trrr... Trrr...".
Parrots are the favourite pet of pirates and supposed to be smart where they can mimic human speeches. They can fly flow and say "TERBAAANG..." and imitate person's speech. When they imitate person's speech, they will say it a bit louder than the original speech. For example, if a person say "Hello!", the parrots will reply "HELLO!". However, if they do not have anyone to talk, they only mumble "HM?".
There is another bird with type Eagle. Eagle cannot be cuddled by any random persons. Otherwise, it will attack the person. Eagle can fly high and can produce voice "Kwaakk....".
The last type of animal is Lion. They like to hunt and produce sound of "Err....". It is difficult to groom lion. When their mood is good, they will produce gentle sound of "Hauhhmm!" when their mane is brused. But when they feel disturbed, they will roar loadly "HAAHUM!!".
The animals should have cage. Javari Park has any size of cages to fit the body of animals. The cages are made specifically from titanium with the size of pad would be adjusted with length of animals' body.
There are two type of cages: Indoor Cage and Outdoor Cage. Indoor cage will contain pet animals whereas outdoor cage will contain wild animals.
Each type has three possible sizes: A, B, C. The details are as follows:
Indoor Cage
- Indoor A has area of 60 cm x 60 cm to fit an animal with body length
<45 cm - Indoor B has area of 60 cm x 90 cm to fit an animal with body length between 45 cm and 60 cm
- Indoor C has area of 60 cm x 120 cm to fit an animal with body length
>60 cm
Outdoor Cage
- Outdoor A has area of 120 cm x 120 cm to fit an animal with body length
<75 cm - Outdoor B has area of 120 cm x 150 cm to fit an animal with body length between 75 cm and 90 cm
- Outdoor C has area of 120 cm x 180 cm to fit an animal with body length
>90 cm
When you arrange the cages, you must classify the cages based on the type of animals. For wild animals such as lion and eagle, their cages are located at outdoor area. Similarly, for pet animals such as cat, hamster, and parrot, their cages are located at indoor area.
After you determined the cages for each animals, your next task is to arrange the placement of cages into 3 levels of row which levels are ground, middle, and upper. You are not allowed to build extra levels. When you are done with the arrangement, move the cages from the highest level to the lowest level. The last step is you have to reverse the order of the cages in each level, by using your own methods (i.e. not using built-in methods in Java).
Your work in this assignment can be summarised as follows:
- Create the suitable classes for this case
- Create other classes to help your comprehension (optional)
- Create the relationship between classes
- Specify instance variables/methods for every classes you create
- Determine whether the instance variables/methods should be static or non-static
- Design cages for every type and size
- Create the class to arrange the placement of cages into 3 levels and
apply this for each type of animals by using array and
ArrayList, then call this behaviour without instantiating any object of this class - Show the result of arrangement of cages
- In the class you create in task (7) above, make another behaviour/method to shift the levels of row and reverse the order of the cages in each level, and call this behaviour without instantiating any object of this class
- Show the result of rearrangement of cages
Please follow the instructions in the root (main) README.
Make sure you write all Java source code files in src/main/java
directory!
The main program in this assignment must be designed to handle user input
from standard input (e.g. prompts from methods calls on a Scanner
object). All output must be displayed to standard output.
Attention: String enclosed within double
*symbols are input given by user
