You’re nearly there! Now, you can create classes right and left, with a side-serving of init blocks and two secondary constructors for dessert. In this lesson, you learned:
- A primary constructor is defined in the class’s header and always executes first.
- A secondary constructor always goes last in the initialization. The initializer blocks kick in before it. There can be many secondary constructors.
- Initializer blocks are literally blocks of code that are executed during initialization.
- Object is an ambiguous term usually used for describing instances of a class, but in Kotlin, it’s also the special class type that implements the Singleton pattern natively.
