The Sincerest Form of Flattery

" summary

Java adds generics (2004), lambdas (2014) and pattern matching (JDK 16+) but keeps type erasure, so generic type info disappears at runtime and arrays of generic types are illegal, causing surprising runtime limits. Java implements lambdas via single-abstract-method interfaces and forbids capturing non-final locals for thread-safety, while Scala implements declaration-site variance, native first-class functions, and partial application with real closures that can capture mutable locals (trading safety for expressiveness).
