A student that completes this project shows that they can:
- craft and manipulate Collections
- craft and manipulate ArrayList Collections
- use and implement interfaces
- use and implement Lambda Expressions
- use and implement abstract classes
Using a combination of abstract classes, an interface, sorting, and lambda expressions, students will create and manipulate a list of animals using object-oriented design principles.
-
Please fork and clone this repository. This repository does not have a starter project, so create one inside of the cloned repository folder. Regularly commit and push your code as appropriate.
-
Create an abstract class for animals
- All animals consume food the same way
- Each animal is assigned a unique number as an id, a name, and a year named, regardless of classification.
-
Methods will return a string saying how that animal implements the action
- All animals can move, breathe, reproduce. How they do that varies by animal type. This variation means that the string that gets returned by a method is different for each animal type (mammals, birds, fish).
-
Create classes for mammals, birds, fish
- Mammals move by walking, breath with lungs, and reproduce via live births
- Birds move by flying, breath with lungs, and reproduce via eggs
- Fish move by swimming, breath with gills, and reproduce via eggs
Hint: think about abstract classes and creating an ArrayList using an abstract class type.
Create a collection for the animals using the following data. You will have one collection of animals; this collection will contain mammals, birds, and fish.
-
Mammals:
Name Year Named Panda 1869 Zebra 1778 Koala 1816 Sloth 1804 Armadillo 1758 Raccoon 1758 Bigfoot 2021 -
Birds:
Name Year Named Pigeon 1837 Peacock 1821 Toucan 1758 Parrot 1824 Swan 1758 -
Fish:
Name Year Named Salmon 1758 Catfish 1817 Perch 1758 -
Using Lambda Expressions and displaying the results to the console:
- List all the animals in descending order by year named
- List all the animals alphabetically
- List all the animals in order by how they move
- List only those animals the breath with lungs
- List only those animals that breath with lungs and were named in 1758
- List only those animals that lay eggs and breath with lungs
- List alphabetically only those animals that were named in 1758
Note: to get your collection to print nicely to the console, you may have to override the toString method on the class that you design.
- Stretch Goal
- For the list of animals, list alphabetically those animals that are mammals.
The MVP of this application would produce the following output.
