One of the best ways to start programming with Phidgets is to use our example code as a guide. Before we get started, make sure you have [[#Install Phidget Drivers for macOS | installed the Phidget drivers]].


==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.


Next, select an example that will work with your Phidget:

Language - Java

MacOS with javac

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.

Install Phidget Drivers for macOS

Before getting started with the guides below, ensure you have the following components installed on your machine:

  1. You will need the Phidgets macOS Drivers
  2. You will need the Java Development Kit from Oracle
  3. You will need a copy of phidget22.jar

Finding Code Samples

To find the code sample to use for your Phidget, navigate to the Code Samples page and select your device from the drop-down menu.

Once you select your device, the code sample generator will give you a working code sample, and a selection of options to customize it to your needs.

Using the Code Samples

To use the code sample from the 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 phidget22.jar in the same folder as your program:

Java mac javac newproject folder.png

Compile and Run

Once you are ready to run your program, open the terminal at the folder location. Next, enter the following command in the command prompt: 

javac -classpath .:phidget22.jar example.java

Finally, enter the following command to run the program: 

java -classpath .:phidget22.jar example
Java mac javac newproject run.png

The project is now using Phidgets!

What's Next?

Now that you have set up Phidgets to work with your programming environment, we recommend you read our guide on Phidget Programming Basics to learn the fundamentals of programming with Phidgets.Next Arrow.png
