A student that completes this project shows that they can:

• implement and use interfaces in Java
• implement and use abstract classes in Java
• implement and use Lambda Expressions in Java

Using a combination of interfaces, abstract classes, and lambda expressions, students will create and manipulate a list of animals using object oriented design principles.

• Create an abstract class for animals

  • All animals consume food the same way

  • Each animal is assigned a unique number, a name, and year discovered regardless of classification.

  • Methods will return a string saying how that animal implements the action

  • All animals can move, breath, reproduce. How they do that, so what string should get returned when the method is executed, varies by animal type.

• Create classes for mammals, birds, fish

  • Mammals move - walk, breath - lungs, reproduce - live births
  • Birds move - fly, breath - lungs, reproduce - eggs
  • Fish move - swim, breath - gills, reproduce - 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

  • Mammals:

    • Name: Panda Year Named: 1869
    • Name: Zebra Year Named: 1778
    • Name: Koala Year Named: 1816
    • Name: Sloth Year Named: 1804
    • Name: Armadillo Year Named: 1758
    • Name: Raccoon Year Named: 1758
    • Name: Bigfoot Year Named: 2021

  • Birds:

    • Name: Pigeon Year Named: 1837
    • Name: Peacock Year Named: 1821
    • Name: Toucan Year Named: 1758
    • Name: Parrot Year Named: 1824
    • Name: Swan Year Named: 1758

  • Fish:

    • Name: Salmon Year Named: 1758
    • Name: Catfish Year Named: 1817
    • Name: Perch Year Named: 1758

• Using Lambda Expressions

  • List all the animals in descending order by year named
  • List all the animals alphabetically
  • List all the animals 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

• Stretch Goal

  • For the list of animals, list alphabetically those animals that are mammals.
