To create JEE project in Eclipse

Create Dynamic Web Project
Under the web contents create your web pages (html files)

You can use Apache Tomcat server to deploy your web application.

To change URL

To change the URL of servlets that you have built, you have to configure web.xml file.

As an example, you have to add following lines to your web.xml file

<servlet>
<servlet-name>helloworld</servlet-name>
<servlet-class>com.amali.surverlet.HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> helloworld</servlet-name>
<url-pattern>/hidden/hello.do</url-pattern>
</servlet-mapping>

If user want to redirect pages without changing URL: they can use RequestDisptacher

Manually Deploy applications

Go to webapps folder in tomcat installation directory
Create a new folder
Copy META-INF and WEB-INF folders from your project folder to the newly created folder
Goto WEB-INF folder and copy classes folder (build-> classes) from project folder
Start the tomcat server

You can build a war file and copy it to webapps folder.Then you can run your application in tomcat server.

Sorting Algorithms

Bubble Sort Named as sinking sort. Compare each pair of the adjacent items and swap them if they are in the wrong order. Worst case and average case time complexity both O(n^2) and best case time complexity is O(n).

JavaScript Objects and Prototypes

Create Objects Using function Create Objects without duplication code: use functions Using constructors To indicate a function is a constructor: append new keyword in front of the function name when executing it Call Property of function object foo.call() = foo() Call can bind different objects and can execute functions __proto__ Copy of prototype object If some property is not in the object itself, it then looks it in the prototype. If it finds it returns the value of that property All the new object instances of function point to same prototype object prototype.constructor: property that points to function GitHub repo: https://github.com/kaosadi17/JavaScript/blob/master/objects%26prototypes.js
