Implementation-independent XML builder.

Configurable number formatter.

This class intended to collect TODO comments from java/c++/etc source files.

Example:

protected readFileData (String path) throws IOException {
// TODO: add try...catch block for IOException
InputStream is = new FileInputStream(path);
...
}


See also DirectoryScanner class.

This class illustrates mixed GUI/command line parameters passing. Any parameter may be specified in the command line. All unspecified parameters will be read using GUI dialog box.

This code illustrates using ruby REXML package. It converts J2EE web application deployment descriptor web.xml into Freemind mindmap document.

I've found it kind of complicated to strip newline chars from a file with just the commandline. This tiny piece of code does just that.

I've found it especially useful when extracting tabulated data from a grabbed site where each cell is on a different html line. This way I can pre-filter the html, remove the newlines, and insert them again at register boundaries (row end in this case), so that with just a couple more replacement from within a regex enabled text editor I can copy&paste it directly to a database.

To create a chatprogram in java we need 2 classes one for Client and one for Server from which the client will be able to connect and exchange text messages. to compile the code simply type these commands in command prompt window:-
1)ipconfig(memorize the Ip address)
2)javac client.java
3)javac server.java
4)java server 10.69.23.203 (You need to type your own ip address)
5) After this you need to open another command prompt window(Make sure the server command prompt window is also open). now type:
java client 10.69.23.203
Thats it.
if anyone have any problems please post a comment and i will answer all of your questions or if you are having trouble in compiling.

This is a very convenient way to remove all doubles from a List in Java. The only prerequisite is that the elements in the list have proper equals and hashCode methods.

It work by using the constructor of a Set that takes a Collection as an argument.

I poured the snippet in a little program so can run it straight away.

A GroovyClassLoader demonstration. The given domain is a german water flow meter system; I think, you shouldn't be able to understand the domain, but you should be able to understand, how to load a Groovy class in Java via a GroovyClassLoader.
