We provide support for the Java language in all major operating systems. We also provide instructions on how to get your project started in a number of common development environments. Select your operating system and preferred development environment below, and follow the instructions to get your project running with Phidgets.
  
=== Documentation ===
+
If you do not know which development environment you want to use, or your development environment of choice is not listed, we recommend starting with javac as the simplest path to getting your code running.

+
General information of how to use Phidgets with Java can be found in the '''Write Code''' section of each development environment page. This information is consistent across all pages.

==Getting Started with Java==
+
If you already know what you're doing and just need the files, you can find them all below.
Welcome to using Phidgets with Java! By using Java, you will have access to the complete Phidget22 API, including events. We also provide example code in Java for all Phidget devices.

====Use our examples====
+
One of the best ways to start programming with Phidgets is to use our example code as a guide. In order to run the examples, you will need to download and install the Java Development Kit from [http://www.oracle.com/technetwork/java/index.html Oracle].
+
  
 +
=== Example Code ===
  
Next, select an example that will work with your Phidget:
 
 
*{{SampleCode|Java|Java Examples}}
 
*{{SampleCode|Java|Java Examples}}
  
 +
===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>
+
 
+
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===
+
====Use our examples====
+
One of the best ways to start programming with Phidgets is to use our example code as a guide. In order to run the examples, you will need to download and install [https://netbeans.org/ NetBeans].
+
 
+
 
+
Now that you have NetBeans installed, select an example that will work with your Phidget:
+
*{{SampleCode|Java|Java Examples}}  
+
 
+
 
+
Next, open NetBeans and create a new project:
+
[[Image:Java_netbeans_newproject.PNG|link=|center]]
+
 
+
 
+
Give your project a name and finish creating the project:
+
[[Image:Java_netbeans_nameproject.PNG|link= |center]]
+
 
+
 
+
Delete the java file that was generated with the project:
+
[[Image:Java_netbeans_deletefile.png|link= |center]]
+
 
+
 
+
Replace the deleted file with the example file that you downloaded. Next, add a reference to phidget22.jar by right-clicking on the libraries folder:
+
[[Image:Java_netbeans_addjar.png|link= |center]]
+
 
+
 
+
 
+
You can find phidget22.jar at the following location:
+
*C:\Program Files\Phidgets\Phidget22\phidget22.jar
+
 
+
 
+
[[Image:Java_netbeans_jarpath.png|link=|center]]
+
 
+
 
+
After pressing run and selecting the main class, the example will be 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!
+

+
 
+
 
+
Finally, drag the example java file into the src folder that has been created for you and run the example:
+
[[Image:Java_eclipse_run.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!

We provide support for the Java language in all major operating systems. We also provide instructions on how to get your project started in a number of common development environments. Select your operating system and preferred development environment below, and follow the instructions to get your project running with Phidgets.

If you do not know which development environment you want to use, or your development environment of choice is not listed, we recommend starting with javac as the simplest path to getting your code running.

General information of how to use Phidgets with Java can be found in the Write Code section of each development environment page. This information is consistent across all pages.

Choose Your Development Environment:
