Which statement is true about modules?

Question

Options

• AAutomatic and unnamed modules are on the module path.
• BOnly unnamed modules are on the module path.
• CAutomatic and named modules are on the module path.
• DOnly named modules are on the module path.
• EOnly automatic modules are on the module path.

• B
  3% (1)
• C
  93% (37)
• D
  5% (2)

Explanation

C is correct because both named modules (JARs/code with an explicit module-info.java) and automatic modules (JARs placed on the module path without a module-info.java) reside on the module path - Java auto-generates a module descriptor for automatic modules based on the JAR filename.

Why the distractors fail:

• A & B are wrong because the unnamed module lives on the classpath, not the module path - it's the catch-all bucket for legacy code that hasn't been modularized.
• D is wrong because it excludes automatic modules, which are very much on the module path.
• E is wrong because it excludes named modules, which are the primary residents of the module path.

Memory tip: Think of it as two worlds - the old world (classpath → unnamed module) and the new world (module path → named + automatic modules). Automatic modules are the bridge: they're legacy JARs promoted into the new world by dropping them on the module path.
