Setting Up Linux (Crostini) on Your Chromebook
To install Java on a Chromebook, you first need to enable the Linux development environment, known as Crostini. This allows you to run Linux applications directly on your Chromebook, providing access to a broader range of software including Java.
Start by opening the Chromebook settings menu and scrolling to the “Linux (Beta)” section. Click “Turn On” to initiate the setup process. You will be prompted to configure a username and disk size for the Linux container; choose values appropriate for your use case. The container typically takes a few minutes to install and configure.
Once Linux is enabled, you can launch the Linux terminal from your app drawer. This terminal is where you will execute commands to install Java and other Linux-based tools. It’s important to keep the Linux container updated to ensure compatibility and security.
Installing Java Development Kit (JDK) in the Linux Environment
With the Linux terminal open, you can proceed to install the Java Development Kit (JDK). The JDK is essential for developing and running Java applications and includes the Java Runtime Environment (JRE) and development tools like compilers.
Use the following command to update the package list and upgrade existing packages:
“`
sudo apt-get update && sudo apt-get upgrade
“`
After updating, install the default JDK package available in the Debian repositories by running:
“`
sudo apt-get install default-jdk
“`
This command installs the OpenJDK version that is recommended for your system. If you require a specific version of Java, such as Java 11 or Java 17, you can install it by specifying the package name, for example:
“`
sudo apt-get install openjdk-11-jdk
“`
or
“`
sudo apt-get install openjdk-17-jdk
“`
Once installation is complete, verify the Java installation by checking the version:
“`
java -version
“`
This command outputs the installed Java version, confirming a successful setup.
Configuring Java Environment Variables
To ensure Java runs smoothly and other applications can locate the JDK, you should configure environment variables such as `JAVA_HOME` and update the system `PATH`.
Begin by finding the installed Java path. You can locate it with:
“`
update-alternatives –config java
“`
This command lists the available Java versions and their paths. Typically, the path looks like `/usr/lib/jvm/java-11-openjdk-amd64/`.
Add the following lines to your `.bashrc` or `.profile` file to set the environment variables:
“`bash
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
“`
Replace the `JAVA_HOME` path with the one matching your installed JDK version. After saving the file, apply the changes by running:
“`
source ~/.bashrc
“`
or
“`
source ~/.profile
“`
These settings ensure the terminal sessions recognize Java commands correctly.
Using Java on Chromebook Linux Terminal
With Java installed and configured, you can compile and run Java programs directly from the Linux terminal. Use a text editor such as `nano` or `vim` to write your Java code. For example, create a file named `HelloWorld.java`:
“`
nano HelloWorld.java
“`
Enter your Java program code, for instance:
“`java
public class HelloWorld {
public static void main(String[] args) {
System.out.println(“Hello, Chromebook!”);
}
}
“`
Save the file and compile it using:
“`
javac HelloWorld.java
“`
This command creates a `HelloWorld.class` file if there are no compilation errors. Run the program with:
“`
java HelloWorld
“`
You should see the output:
“`
Hello, Chromebook!
“`
This workflow demonstrates that Java development is fully functional within the Chromebook’s Linux environment.
