Example text

At line 135, we flip the buffer from reading to writing using the flip() method. The flip() method sets the limit to the current position and the position back to 0. ■■ At line 136, we write the byte buffer to the underlying file. Now we can finish our discussion of NIO by examining how the package implements non-blocking IO. Non-Blocking Server IO Before NIO, Java servers would create a thread to handle each incoming client connection. start(); } More experienced programmers would reuse threads via a thread pool instead of instantiating a new thread each time.

JNDI requires a directory server to be available. Often the directory server is maintained by a separate organization, which may not see value in maintaining the fact that a guy named Marshall likes to have his email messages display their text in hot pink. No matter what your application, there is likely to be something that should be maintained in a more simple fashion. Why not have a solution that handles properties in a hierarchical fashion and is independent of the back end storage mechanism?

Command line check omitted for brevity ... 1 we set the buffer size to be 4 KB. Obviously, given the simple space/time trade-off, we can increase the speed of this for large files by increasing the buffer size. exe Elapsed Time: 13971 milliseconds. 1 are the key workhorse loop of the program where bytes are transferred from the original file to the buffer and then are written from the buffer to a second file (the copy). The FileChannel class includes a method called transferTo() that takes advantage of low-level operating system calls specifically to speed up transfers between file channels.
