8 Test Updated [verified]: Ikm Java
The updated test asks: What is the state of the stream after line 2? Many incorrectly think filtering occurs immediately. It does not. The pipeline is not executed until a terminal operation like count() or collect() is invoked.
The test frequently checks if you understand the contract of functional interfaces. You should be able to distinguish between Predicate , Consumer , Supplier , and Function at a glance. Expect questions that mix these with custom functional interfaces to see if you spot "InvalidMethodDeclaration" errors.
Understand ExecutorService , Callable , Future , and CompletableFuture .

Java 8 fundamentally altered interface design rules. The test frequently checks your knowledge of:
Side-effects in parallel streams and how concurrency impacts performance and order preservation. Interface Enhancements The pipeline is not executed until a terminal
Intermediate operations ( map , filter , flatmap ), terminal operations ( collect , reduce , findFirst ), parallel streams, and stream pitfalls. Optional Class: Proper usage to avoid NullPointerException . Method References: Syntax and usage scenarios.
