Whether you're building Java projects for beginners or pulling them from Github, you'll need to ensure Java is installed on your Raspberry Pi. In this video, I go through easy steps to get either the latest version of Java JDK or Java Open-JDK 8.
I also cover how you can add the JAVA_HOME variable to your Raspberry Pi (Linux) 'environment' file to use open source tools like Apache Tomcat, Maven, and other Java libraries.
=== Commands Used ===
Update Raspberry Pi's package index: sudo apt update
Install latest version of Java: sudo apt install default-jdk
Install Java OpenJDK 8: sudo apt install openjdk-8-jdk
Check Java version (after installation): java -version
Check where Java was installed: sudo update-alternatives --config java
Update 'environment' file: sudo nano /etc/environment
Reboot Raspberry Pi: sudo reboot
#raspberrypi #raspberrypi5 #raspberrypiprojects #raspberrypi4
