Cruising Along with Java: Benefiting from the Modern Features
summary
Covers concrete Java changes since 10: local variable type inference (var) and its pitfalls (don’t use with diamond, needs context), text blocks for multi-line strings, and records as immutable data classes with getters, equals, hashCode and concise construction; recommends compact constructor over canonical for validation/transformation. Explains sealed interfaces/classes with permits and using non-sealed only for testing (keep nonpublic), and shows sealed + records + pattern matching with switch expressions, yield, destructuring, and compiler completeness checks.
