Which two statements are correct about modules in Java? (Choose two.)

Question

Options

• AJava base exports all of the Java platforms core packages.
• Bmodule-info.java can be placed in any folder inside module-path.
• CA module can be packaged in module-info.java file.
• Dmodule-info.java cannot be empty.
• EBy default, modules can access each other as long as they run in the same folder.

• A
  81% (35)
• B
  5% (2)
• D
  2% (1)
• E
  12% (5)

Explanation

A is correct because java.base is the foundational Java module that is implicitly required by all modules and exports all core packages (like java.lang, java.util, java.io) without needing explicit requires declarations.

C is correct because module-info.java is precisely where a module is declared - it holds the module's name, its requires dependencies, and its exports directives, making it the definition file that "packages" a module's metadata.

B is wrong because module-info.java must reside at the root of the module's source directory, not in an arbitrary subfolder - placing it elsewhere causes a compilation error.

D is wrong because module-info.java can be empty in the sense that its body can contain no requires or exports statements - a bare module com.example {} is perfectly valid and compiles fine.

E is wrong because the entire point of the Java Platform Module System (JPMS) is strong encapsulation regardless of location - modules must explicitly exports packages and requires other modules; same-folder placement grants no special access.

Memory tip: Think of java.base as the foundation slab of a building - everything rests on it automatically. And remember module-info.java as the module's passport - it declares who the module is and what it shares. The JPMS slogan is "explicit beats implicit," so any answer suggesting automatic access is always wrong.
