===Libraries===


Copy phidget22.jar from the following location:
{{AllQuickDownloads}}
*C:\Program Files\Phidgets\Phidget22\phidget22.jar
 
 
Place both the example file and the phidget22.jar file in the same location. Your folder should now look something like this:
[[Image:Java_javac_folder.png|link= | center]]
 
 
Open the command prompt at the folder location. Next, enter the following command in the command prompt:
<syntaxhighlight lang="java">
javac -classpath .;phidget22.jar example.java
</syntaxhighlight>
 
 
Finally, enter the following command to run the program:
<syntaxhighlight lang="java">
java -classpath .;phidget22.jar example
</syntaxhighlight>
 
 
[[Image:Java_javac.PNG|link= | center]]
 
 
You should now have the example up and running for your device. Play around with the device and experiment with some of the functionality. When you are ready, the next step is configuring your project and writing your own code!
 
====Configure your project====
When you are building a project from scratch, or adding Phidget functionality to an existing project, you'll need to configure your development environment to properly link the Phidget Java library.
 
 
To include the Phidget Java library, add the following line to your code:
<syntaxhighlight lang="java">
import com.phidget22.*
</syntaxhighlight>

====Configure your project====
When you are building a project from scratch, or adding Phidget functionality to an existing project, you'll need to configure your development environment to properly link the Phidget Java library.
 
 
To include the Phidget Java library, add the following line to your code:
<syntaxhighlight lang="java">
import com.phidget22.*
</syntaxhighlight>
 
You can now compile the file as shown in the previous section.
 
 
The project now has access to Phidgets. Next, view the [[#Write Code | write your own code]] section located below.
 
===NetBeans===
We offer in-depth tutorials on using our examples in NetBeans and Eclipse in the [[#NetBeans|Windows NetBeans]] and [[#Eclipse|Windows Eclipse]] sections.
 
====Installation====
Although Eclipse is standard in the Debian/Ubuntu package repository, NetBeans is no longer standard. What is more, Netbeans does not install by default into a folder within your path.
 
To install NetBeans:
 
1. Download the install script from website: '''<span style="color:#FF0000">http://netbeans.org/downloads/</span>'''
 
2. Change the permissions of the downloaded file to be executable. Usually, this is something like:
 
chmod +x netbeans-7.1-ml-javase-linux.sh
3. Run the downloaded file as a script. (This will result in a GUI interaction that walks you through installation.)
 
4. To find the location where the NetBeans installation occurred, run:
updatedb
locate netbeans
 
5. Usually, the location of the binary is /usr/local/netbeans-7.1/bin/netbeans, where 7.1 is the installed version.
 
====Use our examples====
Once you have NetBeans installed, running our examples will be very similar to the process described in the Windows NetBeans section
 
====Write your own code====
When you are building a project from scratch, or adding Phidget function calls to an existing project, you'll need to configure your development environment to properly link the Phidget Java library. Please see the Windows NetBeans section for instructions if you are unfamiliar with NetBeans.
In your code, you will need to include the Phidget Java library:
 
<syntaxhighlight lang="java">
import com.phidget22.*
</syntaxhighlight>
 
The project now has access to the Phidget function calls and you are ready to begin coding.
 
== Edit the Examples ==
 
By following the instructions for your operating system and compiler above, you probably now have a working example and want to understand it better so you can change it to do what you want. This teaching section has resources for you to learn from the examples and write your own.
Your main reference for writing Java code will be the {{Phidget22API}}.
 
=== Code Snippets ===
 
When programming in Java, you're in luck. All of our code snippet examples on our [[Phidget Programming Basics]] page are in both C++ and Java. Therefore, we do not include any here, because that page is much more in-depth, and you won't have to have two pages open at once. So head over there, and start writing code!
