Interactive code puzzle session walks through JDK 6–16 core pitfalls with live answers and explanations, covering Deque behavior, try-with-resources exception order, streams (peek/limit laziness), lambda effectively-final rules, modules vs reflection (inaccessible object), var/type inference quirks, switch expressions, text blocks, records and pattern matching. Code is provided via the Rafa Don Arrow Star Trek Java Challengers repo and the presenter hands out a free Low Hanging Java Challenges book for further practice.
