Installing OpenJDK 8 JRE on Your Raspberry Pi

If you're a developer or just interested in exploring the world of Java, installing OpenJDK 8 JRE (Java Runtime Environment) on your Raspberry Pi can be a great idea. In this guide, we'll walk you through the process of installing OpenJDK 8 JRE on your Raspberry Pi running the latest Raspbian OS.

Verifying Your Installation

To verify that OpenJDK 8 JRE is installed correctly, open your terminal and type `java -version`. This command will display the version number of the Java installation. For example, you might see something like `openjdk version '11.0.5'`.

Installing OpenJDK 8 JRE

To install OpenJDK 8 JRE on your Raspberry Pi, follow these steps:

1. Update the package list by running the command `sudo apt update`.

2. Install the default JDK (which includes the JRE) using the command `sudo apt install default-jdk`.

Understanding Java and Its Components

Java is a popular programming language used to build different kinds of applications and systems. The Java Development Kit (JDK) is a software development kit that consists of several components, including the Java Runtime Environment (JRE), development tools, and libraries.

The JRE includes the Java virtual machine (JVM), classes, and binaries that allow you to run Java programs. It's the runtime environment that allows you to execute Java code.

Choosing the Right Version of Java

Some Java-based applications may require a specific version of Java, so it's essential to check the application documentation to determine which version is required. If you're unsure which version to install, the general recommendation is to stick with the default OpenJDK (JDK 11) version.

In this guide, we've shown you how to install OpenJDK 8 JRE on your Raspberry Pi running the latest Raspbian OS. With OpenJDK installed, you can start exploring the world of Java development and build a wide range of applications and systems. Remember that OpenJDK is open-source and only permits non-commercial use, such as personal or development use. If you need additional commercial features or a license, Oracle Java may be a better option for you.
