NIO.2 Updates in JDK7

If you are already using the new file I/O API provided in JDK7, you should be aware that there are some minor API changes as of build 64. If you are using the JavaOne Preview release, the changes have not yet been integrated, but they are available now on java.net.

The API is changed as follows:

  • Path.delete(boolean) is now Path.deleteIfExists(). So, delete(true) is equivalent to delete(), and delete(false) is equivalent to deleteIfExists().
  • The time stamp methods in the Attribute class that took long, TimeUnit arguments now take an instance of the new FileTime class. Similarly, the BasicFileAttributes time stamp methods now return an instance of FileTime. The new method signatures are:
    • Attributes.setLastAccessTime(FileRef, FileTime)
    • Attributes.setLastModifiedTime(FileRef, FileTime)
    • FileTime creationTime() in BasicFileAttributes
    • FileTime lastAccessTime() in BasicFileAttributes
    • FileTime lastModifiedTime() in BasicFileAttributes
  • The BasicFileAttribute.linkCount() method has been removed.
  • The BasicFileAttribute.resolution() method has been removed.

The File I/O lesson in the Java Tutorials has been updated with the new API.

Just released -- Java Tutorials update

To coincide with the JDK7 Preview Release and JavaOne, we have just published an updated version of the Java Tutorials. Besides fixing many typos and errors that you have reported, this release includes:

  • An entirely reworked File I/O lesson, featuring NIO.2. This functionality is part of JDK7, which is available now through the Open JDK project on java.net.
  • A new specialized trail covering Sockets Direct Protocol, also new in JDK7.
  • A new facility for gathering feedback about the tutorial. At the bottom of each tutorial page, under the "Discuss" heading, you can leave a publicly viewable, blog-style comment. Let us know what you think about the inclusion of this JS-Kit mechanism.

Thanks, as always, for your feedback. It helps us improve the tutorial!

Converting Pre-JDK7 File I/O Code

Prior to JDK7, the java.io.File class was the mechanism used for file I/O, but it had several drawbacks. Perhaps you have legacy code that uses java.io.File and would like to take advantage of the java.nio.file.Path functionality with minimal impact on your code.[Read More]

PathMatcher in NIO.2

In my last blog entry I show how to walk a file tree using a FileVisitor in a very simple Find example. Alan Bateman (the NIO.2 czar) suggested that, rather than use java.lang.String to match the file, I use the new PathMatcher API. [Read More]
