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.

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 ......................

If you've ever wanted to build an application that can both find the distance between two zip codes, and find zip codes within a specific radius of another zip code, then this is the snippet for you.

I've tried to build this before using PHP4 and MySQL 4 and have found it to be painfully slow for a one-user connection over a Local Area Network (LAN). So, before you continue reading, I must make it abundantly clear that this method requires PHP 5 and MySQL 5.

This is because in PHP5, we will need the MySQL-Improved interfaces, and in MySQL 5, we will need functions and procedures.

Using functions and procedures in MySQL puts the weight of the calculations on MySQL, where they will run hundreds of times faster than if PHP were to attempt to do the work. In addition, using functions and procedures is still hundreds of times faster than carefully crafted SQL statements (one benchmark took over 10 seconds using a WHERE clause, while the function + procedure method took around .12 seconds--note the dot).

Since I am not a mathematician by trade, I found the necessary calculations using Google.

For the "Great Circle Distance" formula, I used Meridian Word Data's website. For the radius finder, I used another that unfortunately I do not have off the top of my head right now. I will look for it again and repost it for proper accreditation.

For the zip code database, I am using the free zip code database from CFDynamics.

Below, you will find the database and table schema, the functions and procedures, and also a demo PHP script to see all of this put into action. As a courtesy, you may download a dump of this database from my website. It's uncompressed size is 3.4M, and it's compressed size is 537K. The checksum is available here.

Please leave me comments, suggestions, questions, and/or rants about this snippet. I feel this is a very useful bit of code, and hope that others out there may find as much use from it as I will be.

The resize_image function allows you to resize a GIF, JPEG or PNG file to any dimension you wish and put an optional black border around the image. Here's an explanation of the arguements:

$image_path: The complete path to the image to be resized

$max_width: Maximum width of the resized image. Leave 0 if you want to specify only the height and have the width auto-scale.

$max_height: Maximum height of the resized image. Leave 0 if you want to specify only the width and have the height auto-scale.

$file_prefix: This will prepend a string onto the resized image filename. If you want to create a thumbnail image and keep the original, set $file_prefix = 'thumb'.

$dir: Allows you to save the resized image to a sub directory under the $image_path directory. If you want to save thumbnail images to images/thumbs, set $dir = 'thumbs'.

$border: boolean, 1 = border, 0 = no border

$mime: Image mime type. (image/jpeg, image/gif, image/png)

daysBeteenDates will calculate the number of days between 2 dates in the form of 'YYYY-MM-DD'.

Simple file upload script.

Open a text file and format it (word wrap).

Pagination Class , I think everyone knew now what's it does and means

NT: This class written by my friend have phun!

Recursively checks for all *.php and *.tpl files in the directory specified (or the current directory if one is not specified) and runs `php -l $file`. Only outputs the errors.

A very simple yet very useful function to have around. Especially generating session codes, filenames or new passwords
