 ## Creating and Manipulating Objects in Java
-In this exercise, we will explore the concept of classes and constructors by imagining and creating objects in Java. Remember, coding is not just about technical skills; it's also a creative process that allows us to bring our ideas to life.

 ### Task 1: Create a Class Describing an Object
 
-Create a new Java file (.java) with a class that represents a physical object of your choice. It could be a person, an animal, an airplane, or anything else you can imagine. Inside the class:
-<ol>
-<li>Declare three variables of three different types that are relevant to your chosen object.</li>
-<li>Initialize these variables with reasonable values. For example, if you chose a "Person" class, you might have variables for name (String), age (int), and height (double).</li>

 ### Task 2: Define a Container Class
 
-Create another Java file (.java) to define a "container" class for your objects. Think of this as a vessel for storing instances of your chosen object. Inside this class:

 ### Task 3: Create a main()-method to create instances of your classes
 
-Create a third Java file (.java) that serves as your main executor-class. In this class:

+><li>Create a third object of your intial class from task 1, outside of your container (i.e. directly in the main()-method). Assign reasonable values to it</li>
+><li>Create a fourth object of your initial class from task 1, outside of your container. Assign it with one of the objects inside the Container object. (<code>Object newObject = object1;</code>)</li>
+>You should now have four variables of your initial class. Two inside of the container, and two outside of the container.

 ### Task 4: Understanding References
 
-<ol>
-<li>Print the reference values of all four variables (the two instances from Task 2 and the new variable from Task 3) to the terminal. This can be done by simply using print(variablename).</li>
-<li>Analyze the results: What do you observe? Why do the reference values behave the way they do?</li>

 ### Task 5: Modifying Variables and Observing Changes
 
-<ol>
-<li>Re-assign the values of the two variables in the Container with new values. For example, if you have a "Person" class, change the name, age, and other attributes.</li>
-<li>Observe the values of the other two variables (the ones outside of the Container). Explain the behavior you see. How do changes to one object affect the others?</li>

 ### Task 6: Constructors
 
-Refactor your code in the Classes and the Main-program such that you have parameterised constructors that you use to create your objects. Let your creativity run free!
