Welcome to using Phidgets with Java! By using Java, you will have access to the complete Phidget22 API, including events.
 
Javac is a command line-based compiler for java programs that compiles java code into bytecode class files.

#You will need a copy of [{{SERVER}}/downloads/phidget22/libraries/any/Phidget22Java.zip phidget22.jar]
 
==Installing Java==
In order to use Java, you will need to download and install the JDK. You can do this by entering the following command in the terminal (where VERSION is replaced with your preferred version number):
<syntaxhighlight lang='bash'>
apt-get install openjdk-VERSION-jdk
</syntaxhighlight>
 
Before continuing, ensure your JDK version matches your JRE version:
<syntaxhighlight lang='bash'>
javac -version
java -version
</syntaxhighlight>
 
{{Finding Code Samples|Java}}
 
==Using the Code Samples==
To use the code sample from the [{{server}}/?view=code_samples&lang=Java Code Samples] page, you can click the '''Download Example''' button to download a Java file with the sample code.

==Setting up a New Project==
Whether you are running our examples or adding Phidget functionality to an existing project, you'll need to configure your development environment to properly link the Phidget Java library.
 
The easiest way to allow Java to access the Phidgets Java library is to place a copy of [{{SERVER}}/downloads/phidget22/libraries/any/Phidget22Java.zip phidget22.jar] in the same folder as your program:

==Compile and Run==
Once you are ready to run your program, 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>

The project is now using Phidgets.
