1Z0-829 Java Platform Overview and Packaging Practice Question
A company wants to distribute a Java desktop application with a bundled JRE for end users who may not have Java installed. Which tool should they use?
⚠ Common exam trap
A common mix-up: candidates confuse jlink (which creates a custom runtime) with jpackage (which bundles the runtime with the application into a distributable installer), leading them to pick jlink because they know it can produce a standalone JRE.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
jpackage
jpackage is the correct tool because it is specifically designed to package a Java application along with a bundled JRE into a native installer (e.g., .exe, .dmg, .deb) for distribution to end users who may not have Java installed. It uses the jlink tool internally to create a custom runtime image and then wraps it with platform-specific packaging tools, ensuring the application runs independently of any pre-installed JRE.
