Question

Options

• AAll three readers are still open.
• BAll three readers have been closed.
• COnly reader1 is closed.
• DOnly reader1 has been closed

• A
  74% (20)
• B
  7% (2)
• C
  4% (1)
• D
  15% (4)

Explanation

All three FileReader objects are open at Line 1 because the code uses a regular try block, not a try-with-resources block - there is no close() call anywhere, and no exception was thrown (all files exist), so the catch block never executes. Options B, C, and D are all wrong for the same core reason: nothing in this code ever closes any reader - not implicitly, not explicitly. Distractors C and D likely tempt candidates who mistakenly think a failed FileReader constructor (e.g., file not found) would close previously-opened readers, but that only affects the reader that threw; and in this scenario, no exception is thrown at all. The memory tip: if the keyword try is immediately followed by a parenthesized resource declaration (try (Reader r = ...)), Java auto-closes it - if there are no parentheses after try, you are responsible for closing manually, and if you don't, resources stay open.
