This README provides instructions for the Java coding track as part of National Coding Week. It will provide step by step instructions for getting your laptop set up and ready to go.
If you are having any problems with the instructions below please come along to the coding picnic slightly earlier and we can help you get your laptops ready.
###1. Install Git
(I already have Git installed, skip me to step 2)
The sample starter code for the event is stored on GitHub . In order to get a copy of the sample code we need to firstly install Git version control.
Follow the instructions on the following pages:
Mac https://git-scm.com/book/en/v2/Getting-Started-Installing-Git#Installing-on-Mac
Windows https://git-scm.com/book/en/v2/Getting-Started-Installing-Git#Installing-on-Windows
Linux https://git-scm.com/book/en/v2/Getting-Started-Installing-Git#Installing-on-Linux
(I already have Java installed, skip me to step 3)
Next step is to install the Java Development Kit (JDK).
Windows
- Navigate to http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
- Click 'Accept Licence Agreement' under the 'Java SE Development Kit 8u51' section.
- Click 'jdk-8u51-windows-x64.exe' to download the 64bit Java version.
- Once the file has downloaded, double click the exe file to begin the installation and follow the instructions on screen
Further details on Windows installation can be found on the Java website.
MAC OS
- Navigate to http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
- Click 'Accept Licence Agreement' under the 'Java SE Development Kit 8u51' section.
- Click 'jdk-8u51-macosx-x64.dmg' to download Java for Mac.
- Once the file has downloaded, double click the dmg file to begin the installation and follow the instructions on screen.
(I already have installed IntelliJ, skip me to step 4)
To make things a little easier we'll make use of an Integrated Development Environment (IDE) called IntelliJ.
- First navigate to the JetBrains website and download the community edition of IntelliJ
- Follow the installation and set up instructions
###4. Clone the tutorial code base
(I have already cloned the code, skip me to step 5)
The final preparation step is to clone the source code from GitHub.
-
Start IntelliJ and you should see a screen similar to figure 1 below. Figure 1
-
Click 'Check out from Version Control' and you should be presented with a screen similar to figure 2.
- Git Repository URL https://github.com/eggsy84/java-webapp-coding-week.git
- Parent Directory Choose a directory on your machine
- Directory Name java-webapp-coding-week
Figure 2
- Click Clone
###5. Start your web application
(I have already started the web application, skip me to step 6)
Once the code has been cloned to your machine, we can do the fun part and start up the application.
- Click the 1 : Project link shown in the top right of the IntelliJ screen
Figure 3
- Navigate to the Java file called Application
Figure 4
- Right click the file
- Click Run Application.main()
- You should start to see output of the application starting up.
###6. View your web application
Open up your favourite web browser at go to:
http://localhost:8080/greeting?name=java
Try replacing 'java' with your name ;)
