Discover Modern Java
summary
Covers Java 7–15 with live demos and bytecode-backed claims: shows bytecode inspection for switch-on-String and lambdas, demonstrates that lambdas create synthetic methods and runtime classes and that they can be serialized if the target functional interface is serializable, proves single-file execution (java file run directly) and jpackage producing native bundles, explains modules blocking deep reflection, and highlights preview features (switch expressions, text blocks), records replacing boilerplate POJOs, var type-inference caveats, and the new HTTP client.
