Gain insights into Java programming by exploring conditional statements, loops, math, logic, inheritance, generics, and arraylists, to become an intermediate Java developer.

Learn Java for free with this interactive course, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover common concepts such as Conditional Statements, Loop Statements, Math, and Logic in Java, before moving on to more advanced concepts like Inheritance, Generics, and ArrayLists, along with much more.

By the time you're done, you'll be an intermediate level Java developer, ready to take on your own projects.

# Problem statement

Whenever you visit a zoo, there are many types of animals in it. However, for each animal some things never change- they all have a name and an age. Also a country of origin. This time, we want you to use the concept of classes and inheritance to solve the exercise below!

# Coding exercise

The code below has:
* A **parent** *class* named `Animal`. 
  * Inside it *define*: 
    * `name`  
    * `age` 
    * `set_data(int a,string b)`:
      * sets `age` and `name` parameters and to the given values.

   

* Then  there are **two** **derived** *classes* 
  * `Zebra`  
  * `Dolphin` 

* The **derived classes** should 
  * Return a string containing a *message* telling the `age` and the `name` as well as information about *place* of **origin** of that *animal*.
    * **Hint**: You have to create **two** *separate* *message functions* for both the **base** classes.
    * **Hint**: The origin of Zebra is Africa, and the origin of Dolphin is New Zealand. 

## Example

* The `animal_type` named `name` is `age` years old. The `animal_type` comes from `origin`.

* If we have an animal of class `Zebra`, whose name is `Z` with age, `2` and the country name `Africa`. The output should be as follows: 

> <font size="3" color="maroon">The zebra named Z is 2 years old. The zebra comes from Africa
</font>

In this challenge, can you extend a parent class with one function overridden for each child?
