1Z0-829 Java I/O API and Securing Applications Practice Question
Which statement about java.io and java.nio.file packages is true?
⚠ Common exam trap
Candidates often confuse the legacy java.io.File class with the modern java.nio.file.Path interface, assuming Path is in java.io because both deal with files, or they mistakenly think java.nio.file is deprecated due to its 'nio' naming, when in fact it is the recommended API.

Correct answer & explanation
✓
The java.nio.file package provides support for symbolic links and file attributes
The java.nio.file package (part of NIO.2) explicitly provides support for symbolic links via methods like Files.createSymbolicLink() and Files.isSymbolicLink(), and it offers comprehensive file attribute access through classes like BasicFileAttributes, DosFileAttributes, and PosixFileAttributes, which are not available in java.io.
