Understanding your current Java setup is the first step toward building custom solutions that seamlessly interface with existing drone platforms and push the boundaries of what’s possible.
Practical Methods to Identify Your Java Version
Determining your Java version is straightforward and can be done through several methods, depending on your operating system and specific needs.
Using the Command Line Interface (CLI)
The command line is the most reliable and universally applicable method to check your Java version, providing precise details about the installed JRE or JDK.
Windows
- Open Command Prompt: Press
Win + R, typecmd, and press Enter. - Execute Command: Type
java -versionand press Enter. - Interpret Output: The output will display the Java runtime environment version, build number, and potentially other details. For example:
java version "1.8.0_301"
Java(TM) SE Runtime Environment (build 1.8.0_301-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.301-b09, mixed mode)
In this example, “1.8.0_301” indicates Java 8, update 301. For newer versions (Java 9 and above), it might look like:
openjdk version "11.0.12" 2021-07-20
OpenJDK Runtime Environment (build 11.0.12+7-LTS)
OpenJDK 64-Bit Server VM (build 11.0.12+7-LTS, mixed mode)
Here, “11.0.12” denotes Java 11.
macOS/Linux
- Open Terminal: On macOS, go to
Applications > Utilities > Terminal. On Linux, use your distribution’s terminal application. - Execute Command: Type
java -versionand press Enter. - Interpret Output: The output format will be similar to Windows, showing the Java version and runtime details.
Note on javac -version: If you are a developer using a JDK, you can also type javac -version in the command line. This command specifically checks the version of the Java compiler, confirming your JDK installation. If only java -version works, you likely only have a JRE installed.
Checking Through the Java Control Panel (Windows)
For Windows users, the Java Control Panel provides a graphical interface to manage Java settings, including viewing the installed versions.
- Open Control Panel: Search for “Control Panel” in the Windows search bar and open it.
- Navigate to Java: Depending on your view settings, find and click on “Java” or “Programs” then “Java”. This will open the Java Control Panel.
- View Version Information: In the Java Control Panel, go to the “Java” tab and click on the “View…” button under “Java Runtime Environment Settings.” This window will list all installed JREs and their versions.
This method is useful for identifying multiple installed JREs, which is common in complex development or application environments.
Locating Java within Application Directories
Sometimes, specific drone-related software might bundle its own Java Runtime Environment within its installation directory to ensure compatibility, preventing conflicts with system-wide Java installations.
- Navigate to Application Folder: Go to the installation directory of your ground control station, mapping software, or SDK.
- Search for
java.exeorjrefolder: Look for a subfolder namedjreorbincontainingjava.exe(Windows) orjavaexecutable (macOS/Linux). - Run Version Command (if applicable): If you find an executable, you can often run
[path_to_java_executable] -versionfrom the command line to check its specific version, ensuring you’re querying the bundled Java, not the system-wide one. This method is particularly useful when troubleshooting issues specific to one application.
Best Practices for Managing Your Java Environment in Drone Tech
