It logs in, changes status to online, creates a new IM session with the target user, sends the message and ends both connections.

It involves the use of two Java classes, the Runtime class and the Process class. Basically, you use the exec() method of the Runtime class to run the command as a separate process. This returns a Process object for managing the subprocess. Then you use the getInputStream() and getErrorStream() methods ofhttp://freecode-freecode.blogspot.com/2008/06/how-to-run-external-system-commands-in.htmlnoreply@blogger.com (freecode)tag:blogger.com,1999:blog-3550559392700243747.post-216560513292985872Wed, 11 Jun 2008 09:01:00 +00002008-06-11T02:05:43.875-07:00javamultithreadingThis is the server and the client program thatI wrote basically it gives u a good understanding of how sockets work in java . /*This is the server for the MultiThreadedChatClient program thatI wrote basically it gives u a good understanding of how sockets work in java Author: Mohammed Alfaaz email:alfaaz@gmail.com */ import java.io.*; import java.net.*; public class MultiThreadChatServerhttp://freecode-freecode.blogspot.com/2008/06/multi-threaded-programming.htmlnoreply@blogger.com (freecode)tag:blogger.com,1999:blog-3550559392700243747.post-344149709205429036Tue, 10 Jun 2008 14:41:00 +00002008-06-10T07:51:24.030-07:00javawatermarkThe tool to adding watermark to images,recommended markImage () methods to create watermark image.

What we do is to create an input stream from the file we want to compress, and while we read from it we write the contents to an output stream. This output stream is of type ZipOutputStream which takes an FileOutputStream as parameter. Next we have to add a zip entry to the output stream before we start writing to it.

Now it should be said that if you want to write text to a file you should probably find it easier to go with a Writer class like the BufferedWriter instead. The write method of the BufferedOuputStream takes either a byte array or an int as argument so that is why we have to call getBytes() on any String that we provide tohttp://freecode-freecode.blogspot.com/2008/02/write-to-file-using-bufferedoutputstrea.htmlnoreply@blogger.com (freecode)tag:blogger.com,1999:blog-3550559392700243747.post-1058054979031097972Thu, 21 Feb 2008 14:28:00 +00002008-02-21T06:29:14.725-08:00javaThis example shows how to read the contents of a file using a BufferedInputStream. There are a couple of ways to do so, and in this example we use a byte array to store the data read. We loop through the file contents and fill out buffer up to the size of the buffer array until there are no more data left to read. It possible to read from the file one byte at a time, but to use a buffer is more http://freecode-freecode.blogspot.com/2008/02/read-from-file-with-bufferedinputstream.htmlnoreply@blogger.com (freecode)tag:blogger.com,1999:blog-3550559392700243747.post-6596629326079899440Thu, 21 Feb 2008 14:14:00 +00002008-02-21T06:26:45.897-08:00javaIn this example we read the lines of a comma separated file and split the values into an array.
