What peaked my interest was the last sentence of the documentation: Interfaces, Interfaces, InterfacesĪ quick glance at Kotlin’s documentation provides a good overview about what the difference between them is: while List provides read-only access to stored elements, MutableList provides “list-specific write operations” that allow us to add or remove particular elements from an existing list. While I have been unsuccessful in my attempts, with the particulars of what I want to do, I learned quite an interesting amount about what makes a List different from a MutableList, and I’ll share a bit more about what I’ve learned here. My last attempt involves casting immutable lists as mutable lists, in order to modify a supposedly immutable list into a mutable one. I can almost feel your excitement through this screen! In particular, I’ve been trying to investigate and learn ways in which you can break immutability in Kotlin, either knowingly or unknowingly. I’ve been thinking about immutability a lot…interesting, I know.
