Modern Java: Beyond Version 8
summary
Shows how Java 8 test code for verifying an accounts table gets shorter and safer using var for local type inference, Streams instead of loops, and new Stream ops that turn an 11-item list into 3 with takeWhile or into 8 with dropWhile. Demonstrates switch expressions (arrows and yield) to return IDs, replaces POJOs with records, embeds JSON with text blocks, and uses List.of/Map.of; examples use Selenium-style web elements and Java 9–16 features.
