Choosing the Right Method
- For simple file existence checks on a standard local file system, either the java.io.File or java.nio.file.Files method will do the job.
- If you need more advanced features or performance optimizations, the java.nio.file.Files method is recommended.
- For files on HDFS, use the HDFS API as shown.
