Overview

Eclipse

Eclipse is an open source community whose projects are focused onproviding a vendor-neutral open development platform and application

frameworks for building software. The Eclipse Platform is written in theJava language and comes with extensive plug-in construction toolkits

and examples. It has already been deployed on a range ofdevelopment workstations including Linux, HP-UX, AIX, Solaris, QNX,Mac OS X and Windows based systems. -www.eclipse.org

Eclipse is a free, open source, platform-independent softwareframework. This framework has been used to develop an IDE for Java.

Download and Installation

Eclipse can be downloaded from http://www.eclipse.org/downloads.This link automatically detects your OS and provides the latest releaseof Eclipse for your platform(You can also browse other builds by clicking on 'All Versions'). Choosea mirror and save the zip file. Eclipse comes as a zipped dump ratherthan an installation. All you need to do is just unzip it to a preferredlocation and you can start using it.

If you are using Linux, you need to append this location to youpath. You can add this line below to .bashrc file in your home toopen Eclipse from shell.

export PATH=$PATH:/usr/local/eclipse

Here Eclipse is assumed to be unzipped to /usr/local.

In windows system, you can just copy the link to Eclipse executable toyour start menu to access it.

Add a new Java class to this project:


9/16

Name the class and check the public static void main option and clickFinish.


10/16

This will take you to code window where you can enter the sampleJava code. (Note that function help pane is opened while typing thecode.)


11/16

In Eclipse, Projects are automatically built while coding. This helps inidentifying syntax errors while coding. You can change this option inProject menu.


12/16

As the project is build, now its time to run the code:

Go to Run Menu > Run and it opens a run configuration chooser if youare running the project for the first time.


13/16

Choose the type of application you are developing and create a newconfiguration of that type by double clicking on it. In our case, it is asimple Java application and we are creating a new configuration underJava Application.


14/16

Once you choose the application type, we need to specify the mainfunction to start with. We can either specify it manually or use search.Pressing Search button pops up the following window. You can seethat the main function is already found. If we have multiple mainfunctions, we can choose the one to run initially.


15/16

Bingo!We successfully created a Java application using Eclipse.
