This chapter is smaller, but it still rewards exact rule awareness. Most questions here are really asking what a platform feature is asserting, exposing, or packaging.
Annotation-and-tool map
If the stem is mainly about…
Better first instinct
override correctness
@Override behavior
lambda-target legality
@FunctionalInterface expectations
locale-specific text lookup
resource-bundle resolution
packaging or runtime image tools
know whether the tool analyzes, links, or packages
What the exam is really testing
If the code or tooling shows…
Strong reading
built-in annotations
compiler intent and API signaling are the point
resource bundle names
locale resolution and fallback matter
packaging tool names
deployment purpose is under test
Common traps
Trap
Better rule
thinking annotations automatically rewrite business logic
many are declarative or compiler-facing
treating resource bundles like plain files with no fallback behavior
