1 Introduction Java Course 2018

Local Environment Setup
If you are still willing to set up your environment for Java programming language, then this section guides you on how to download and set up Java on your machine. Following are the steps to set up the environment.

Java SE is freely available from the link Download Java. You can download a version based on your operating system.

Follow the instructions to download Java and run the .exe to install Java on your machine. Once you installed Java on your machine, you will need to set environment variables to point to correct installation directories −

Setting Up the Path for Windows
###pc:\Program Files\java\jdk directory −

Right-click on 'My Computer' and select 'Properties'.

Click the 'Environment variables' button under the 'Advanced' tab.

Now, alter the 'Path' variable so that it also contains the path to the Java executable. Example, if the path is currently set to 'C:\WINDOWS\SYSTEM32', then change your path to read 'C:\WINDOWS\SYSTEM32;c:\Program Files\java\jdk\bin'.

Setting Up the Path for Linux, UNIX, Solaris, FreeBSD
Environment variable PATH should be set to point to where the Java binaries have been installed. Refer to your shell documentation, if you have trouble doing this.

Example, if you use bash as your shell, then you would add the following line to the end of your '.bashrc: export PATH = /path/to/java:$PATH'

Popular Java Editors
To write your Java programs, you will need a text editor. There are even more sophisticated IDEs available in the market. But for now, you can consider one of the following −

Notepad − On Windows machine, you can use any simple text editor like Notepad, TextPad.

Netbeans − A Java IDE that is open-source and free which can be downloaded https://www.netbeans.org/index.html

Eclipse − A Java IDE developed by the eclipse open-source community and can be downloaded from https://www.eclipse.org/.
Steps to Install Eclipse
We've recently introduced the Eclipse Installer, a new and more efficient way to install Eclipse. It is a proper installer (no zip files), with a self-extracting download that leads you through the installation process. For those who prefer not to use the Installer, the packages and zip files are still available on our package download page.

1. Download the Eclipse Installer
Download Eclipse Installer from http://www.eclipse.org/downloads

Eclipse is hosted on many mirrors around the world. Please select the one closest to you and start to download the Installer

2. Start the Eclipse Installer executable
For Windows users, after the Eclipse Installer executable has finished downloading it should be available in your download directory. Start the Eclipse Installer executable. You may get a security warning to run this file. If the Eclipse Foundation is the Publisher, you are good to select Run.

For Mac and Linux users, you will still need to unzip the download to create the Installer. Start the Installer once it is available.

3. Select the package to install
The new Eclipse Installer shows the packages available to Eclipse users. You can search for the package you want to install or scroll through the list.

Select and click on the package you want to install.

4. Select your installation folder
Specify the folder where you want Eclipse to be installed. The default folder will be in your User directory.

Select the ‘Install’ button to begin the installation.

5. Launch Eclipse
Once the installation is complete you can now launch Eclipse. The Eclipse Installer has done it's work. Happy coding.
