Question 348 of 513
1Z0-829 Java Platform Overview and Packaging Practice Question
Which TWO statements are true about Java modules in Java 17? (Choose two.)
⚠ Common exam trap
Oracle often tests the misconception that all packages in a module are automatically exported, but in reality, only explicitly exported packages are accessible outside the module, and the jlink tool creates a runtime image, not a JAR file.
Answer choices
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
✓
A module can export a package only to specific modules using 'exports ... to ...'
The 'exports ... to ...' directive in module-info.java restricts the exported package to only the specified target modules, providing fine-grained access control. This is a key feature of the Java module system introduced in Java 9, allowing a module to expose its packages only to trusted modules rather than all other modules.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A module can export a package only to specific modules using 'exports ... to ...'
Why this is correct
Qualified exports limit access to specified modules.
- ✓
The module-info.java file must be compiled with javac and placed in the root of the JAR.
Why this is correct
module-info.class must be at the root of the modular JAR.
- ✗
All packages in a module are automatically exported.
Why it's wrong here
Only explicitly exported packages are accessible outside the module.
- ✗
The jdeps tool can be used to create a module graph.
Why it's wrong here
jdeps analyzes dependencies but does not create graphs directly.
- ✗
The jlink tool creates a JAR file containing the module.
Why it's wrong here
jlink creates a runtime image, not a JAR.
