| 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.

| ==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 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>
| |
| | |
| Now that you have the JDK installed and phidget22.jar on hand, select an example that will work with your Phidget:

| | |
| Your project folder should now look something like this:
| |
| [[Image:Java_javac_linux_folder.PNG|link=|center]]
| |
| | |
| | |
| Next, open the terminal at the folder location and enter the following command:
| |
| <syntaxhighlight lang='bash'>
| |
| javac -classpath .:phidget22.jar example.java
| |
| </syntaxhighlight>
| |
| | |
| Finally, enter the following command to run the program:
| |
| <syntaxhighlight lang='bash'>
| |
| java -classpath .:phidget22.jar example
| |
| </syntaxhighlight>

| ==Setting up a New 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.
| |
| | |
| 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>
| |
| | |
| You will also need a copy of [{{SERVER}}/downloads/phidget22/libraries/any/Phidget22Java.zip phidget22.jar].
| |
| | |
| Create your new project folder and java file, and place phidget22.jar in the same folder as your new project file. Your folder should look somehting like this:
| |
| [[Image:Java_javac_linux_folder_new_project.png|link= | center]]
| |
| | |
| To use the Phidget Java library, add the following import to your code:
| |
| <syntaxhighlight lang="java">
| |
| import com.phidget22.*;
| |
| </syntaxhighlight>
| |
| | |
| 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>
| |
| | |
| [[Image:Java_javac_linux_new_project.PNG|link= | center|850px]]
| |
| The project now has access to Phidgets.
