Makes a package accessible to other modules
Specifies a dependency on another module
Allows reflective access to a package at runtime
Declares a service implementation
Specifies a service interface consumed by the module
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
requires: Specifies a dependency on another module.
Correct matches: requires specifies dependencies, exports grants compile-time access, opens enables reflective access, provides declares service implementations. Common confusion is between exports and opens due to their related but distinct roles.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
requires: Specifies a dependency on another module.
Why this is correct
The requires directive declares that the current module depends on another module.
exports: Makes a package accessible to other modules.
Why this is correct
The exports directive makes a package accessible to all or specified modules at compile time.
opens: Allows reflective access to a package.
Why this is correct
The opens directive allows reflective access to a package's types and members at runtime.
provides: Declares that the module provides an implementation of a service.
Why this is correct
The provides directive declares that the module provides an implementation of a service interface.
exports: Allows reflective access to a package.
Why it's wrong here
Incorrect — exports provides compile-time access, not reflective access; that is the function of opens.
opens: Makes a package accessible to other modules.
Why it's wrong here
Incorrect — opens provides reflective access, not compile-time accessibility; that is the function of exports.
