Introspection again I really don't know where you are getting the idea that you can't introspect class files. Only languages compiled to assembler would have issues with late binding. The JVM has no issues with Late binding because it uses dynamic dispatch so I have no idea what you are talking about here. Constraints are quite easy to implement on the JVM using bytecode libraries like Spoon or using aspects. Those are all issues with Java and its syntax. I know of no real issues with the JVM related to any of the points you raised.
I hope MS is paying you well for your trolling. Which is an ironic statement given the biggest problem with Kotlin over many other languages is that it suffers from being born from the JVM and so inherits it's countless legacy issues.

with Java has made it that people can kind of progressively move code bases over and it would be great to get to the point down the road, where just everything is all Kotlin."
We know that they're more productive, the quality of applications is higher and so getting more of those people to move more of their code over has been a focus for us. "We know that developers are generally more satisfied with Kotlin than with Java. "There is still quite a bit of Java still happening on Android," Ward said.
JETBRAINS ANNOTATIONS ANDROID
It's no surprise that Google's hope is that over time, all Android developers will switch over to Kotlin. Back in 2018, Google and JetBrains also teamed up to launch the Kotlin Foundation.Įarlier this week, I sat down with Google's James Ward, the company's product manager for Kotlin, to talk about the language's role in the Android ecosystem and beyond, as well as the company's future plans for it. Since then, Google took this a step further by making Kotlin its preferred language for writing Android apps in 2019 - and while plenty of developers still use Java, Kotlin is quickly becoming the default way to build apps for Google's mobile operating system. I hope that by applying this solution, you will love them more.An anonymous reader shares a report: It's been just over five years since Google announced at Google I/O 2017 that it would make Kotlin, the statically typed language for the Java Virtual Machine first developed by JetBrains, a first-class language for writing Android apps. Use cases are a crucial part of clean architecture, and developers always had a love/hate relationship with them.
Scalability: if the repository method requires extra parameters that are not coming from the presentation layer, all the VMs using the use case won’t need to be updated because they are protected by the use case interface.No redundancy: a change to the repository method will not require a Use Case change.In Dagger, if you have multiple suspend () -> Answer, String> you won’t be able to do the following: fun provideGetSomeModelUseCase( someModelRepository: SomeModelRepository ): GetSomeModelUseCase Pros Overall, this was a good approach since it removes boilerplate, but given that most Android projects are heavily influenced by DI frameworks like Koin and Dagger, which require types to work, this approach came with an additional complexity for the DI layer. Approach 3: Functional Use Cases With Type AliasesĪ while ago, I came out with the Functional Use Case approach, where you have a function or a type alias instead of having an interface for the Use Case.īecause you don’t have an interface but a higher order function, you can inject whatever you want therefore, swapping a repository method for a use case class is just a matter of updating the DI layer.
In pure OOP, these two approaches are the only options you have but when you add functional programming to the mixture, things change for the better. NB: when I say “parameters coming from the presentation layer” I don’t mean presentation models passed to the use case, I mean input coming from the presentation layer that is mapped into domain models.

Redundancy: if your repository method signature changes for getting different parameters from the presentation layer, you will have to update the use case class, tests, and interface.Scalability: if the repository method requires extra parameters not coming from the presentation layer, all the VMs using the use case won’t need to be updated because they are protected by the use case interface.
