There are several languages which are powered by the JVM. What are the main differences between their type systems? This session will compare bytecode generated by Java, Kotlin and Scala, analyse compilation and execution time, and explore the behaviour of generics and type inference. We will compare and contrast code samples to help understand how each of these languages handle types.
