The Amazing Features of Modern Java

on YouTube ↗01h 02m

" summary

Recent Java work moves from Java 8 and modules to a six‑month release train, letting big items finish (type inference took ~5 years, Project Loom ~12 years) and land when ready. Concrete features shown: switch expression with yield removes break errors and enables pattern matching; text blocks are compiler syntax sugar (bytecode still LDC strings) for multi‑line strings; records as data classes give immutable tuples with generated ctor/equals/hashCode/toString; sealed hierarchies plus permits enforce closed families; pattern matching with instanceof removes manual casting. Live coding demonstrates all compile and behave as described.
