I had searched high and low for a way to generate a palette of web-safe colors. Despite Google's best efforts, what I had found was lacking for my needs. So, I decided to write a library that would generate all 216 web safe colors, and then allow me to manipulate those colors in any way that I chose.
If anybody is curious as to why I would want to do something so... simple, it is because I needed a very light-weight color picker, and didn't want to mess with any fancy options.

Similar to Perl's CGI::escapeHTML(), though (because we can!) this adds it as a method to all String objects.

It works with Array types. The example is a simple list of numbers, but the array could contain anything; lists of strings, functions, DOM nodes, whatever. Unfortunately, a lot of things that seem like arrays in the DOM aren't really, so you can't shuffle the images on a page with just document.images.shuffle() all by itself.

What is Dijkstra Algorithm? click on the link above and first understand what the algorithm is all about. in short it calculates the shortest path from A to F or vise versa. This code i can guarantee is the simplest and easiest code to understand. just search on google and try to compare this code and other dijkstra code and you will see what i am talking about. i spent alot of time myself and my instructor to guide me on the rite path.
http://en.wikipedia.org/wiki/Dijkstra%27s_algorithm(Description)
to see how the algorithm really works go on this website it tells you step by step how to update the cost and which path to choose.
http://renaud.waldura.com/doc/java/dijkstra/
Please give some time to understand the algorithm first and then you can see my code. if you done understand the algorithm it is very useless. i know alot of people need Dijkstra algorithm in java for their HW assignment or Test. i am giving you the solution step by step. anyone who wants to understand please go to the url i have posted above and once you have understand then run the code and for those people who just want to copy so that they can get 90% in their test No Problem Here it is
.
First open a notepad and name that file anything like data.txt or datas.txt and make sure the file looks something like this and in this format.
0 3 100 5 100 100 (100 represents infinity)
3 0 6 7 7 100
100 6 0 5 5 3
5 7 5 0 1 100
100 7 5 1 0 2
100 100 3 100 2 0
i name this file as a data.txt file. i have 6 nodes. and A is always the starting node which has the cost of 0 so by looking at the first line i
know that A to A have distance 0, A to B is 3, A to c is Infinity, A to D is 5, A to E is Infinity(means no edge connected with A), A to F is Infinity.
for second line(B to A is 3, and then vise versa) and for the 3rd line it starts for C and etc..
save the txt file by any name and then copy the code which i have posted and then to run type this:
javac routing.java
java routing data.txt
you will get the output. i will say this one more time understand how the algorithm works or ......................

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 an analog clock script designed to jump in place of a div element of class 'analogclock'.
The div tag is not replaced in this custom element, but instead is used as a pseudo-document to hold the clock itself. The 'hands' are implemented using arrays of generated divs.
I was actually inspired to write this widget because of an article on About.com's Javascript pages written by a guy named Stephen Chapman. His code was a mess, but I only discovered this after delving through two layers of 'unescape()' obfuscation.
The basics: You control the look of the numbers and the 'box' model of the clock using basic CSS. You control the clock's size (it will always be square) using the 'size' attribute.
The 'seconds', 'minutes', and 'hours' attributes are for the color of the 'hand's. 'numstyle' can be 1, i, I, or '.', each refering to a different type of face-numbering for the clock
The 'localzone' attribute tells the script to use the user's local time zone. If it's '0', 'false' or 'no', the clock will use the 'clockzone' attribute to determine what time it is (the clock zone is relative to GMT, so, for example, US Eastern is -5. The clock automagically figures out if we're in DST, so you don't have to.)
The 'city' and 'country' are for if you want to put in the city/country of origin for your clock. To be honest, you can put anything there.
Lastly, I designed my version of the clock to be able to not 'tick', i.e., work like the old-school analog clocks. If you want ticking, add 'tick=1' to the attribute list
As with all of my widgets, the idea here is that you can just include the .js file and start dropping in tags without needing to know any ECMAScript at all.
Additionally, for you ECMAScripters, I was very careful to keep my pollution of the global namespace to one class: analogClock.

This is a simple script to provide basic cross-platform XML request functionality in Javascript. It's meant to be the core component in any AJAX style framework. It is not an instantiable object, but instead is a namespaced microlibrary.
Calling is easy:
XMLRequest.GET(uri, query, callback, fallback)
uri: The location you're after
query: an associative array of form data to provide via the URL
callback: callback function of the form myCallbackFunction(objXMLHttpRequest), which is called upon successful (response = 200 OK) retrieval of the XML data
fallback: myFallbackFunction(objXMLHttpRequest), which is called upon failed (response != 200 OK) retrieval of the XML data.
XMLRequest.POST(uri, query, form, callback, fallback)
Similar, but does the query using the POST method. 'query' is the URL-appended data, still in associative array form, and 'form' is the same for the POST data.

This is a brief revision to my previous snippet. It is still what it was: a small, simple system for using XMLHttpRequest without using globals.
I'll put the API spec in the code this time, so as not to clutter the front page further.
Changes:
I'll put the API spec in the code this time, so as not to clutter the front page further.
Changes:
Changed name to HTTPRequest (far more accurate)
Added HEAD requests
Shortened code by making a GenericRequest function
Used a better method for getting an XMLHttpRequest object (checks multiple MS versions and implements the latest one)
