Exercises

Now that you understand instance properties, type properties, and methods, it is time to spend some time in the Playground creating new classes and instances:

• Exercise 1: Create the mutable versions of the following three classes that we analyzed in Chapter 1, Objects from the Real World to Playground:

  • Equilateral triangle (The EquilateralTriangle class)

  • Square (The Square class)

  • Regular hexagon (The RegularHexagon class)

• Exercise 2: Create the immutable versions of the previously created classes
