Enhancements in Java SE 7

The java.nio.file package and its related package, java.nio.file.attribute, provide comprehensive support for file I/O and for accessing the file system. A zip file system provider is also available in JDK 7. The following resources provide more information:

In addition, the following enhancement is introduced:

Area: NIO
Standard/Platform: JDK 7
Synopsis: Prior to the JDK 7 release, direct buffers allocated using java.nio.ByteBuffer.allocateDirect(int) were aligned on a page boundary. In JDK 7, the implementation has changed so that direct buffers are no longer page aligned. This should reduce the memory requirements of applications that create lots of small buffers.
