The standard Raspbian repositories include two different Java packages. Java Runtime Environment (JRE) and Java Development Kit (JDK). JRE includes the Java virtual machine (JVM). classes. and binaries that allow you to run Java programs. JDK consist of JRE and development/debugging tools and libraries necessary to build Java applications.

If you are not sure which Java package to install. the general recommendation is to stick to the default OpenJDK (JDK 11) version. Some Java-based applications may require a specific version of Java. so you should consult the application documentation.
