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.

I was looking for an easy way to populate a combo box with strings taken from an enumeration, and also to be able to pull out Enum objects from the combo box. After some searching, I found EnumComboBoxModel on the JDesktop website, but was not able to find any code.

Instead I came up with an easier solution that did not require me to define a new Model class, but instead uses javax.swing.DefaultComboBoxModel.

Sorry for the disorganization of the code, but hopefully you get the idea.

Customize JSlider Labels

Draws a line (with arrow head) between two given points.

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);
...
}

This function returns a Date object being set at 12 A.M. It is useful for comparing dates where you don't know if they'll come set at the beginning of the day or not.

More often than not, if your trying to work out what's going wrong with your subclass of InputStream, why the character encoding is getting lost in your database, or your file format reader is failing, you'll need to dump a byte buffer out in a useable form.

Here's two methods, one which appends to a StringBuffer, one which simply prints out to System.out

(NB: The line: sb.append( "n" ) ; SHOULD have a leading slash ie: sb.append( "\n" ) ; but the formatter seems to remove it...

I use something similar to this in an application named Shock 3. It provides you with your own Custom settings that can handle your own Custom types as well.

Here's a nifty trick I often use for testing.

Lets say you have a c:\foo\lib directory full of jarfiles for log4j, javamail...whatever.

Modern J2EE containers do a nice job of letting you deploy a jarfile with your code and have a lib directory full of jarfiles like this, but what if you just want to run a quick client from the command line?

Here's what you do:
