Liberica JDK – a free, supported, and 100% open-source distribution of OpenJDK, verified by TCK for Java SE.

In this video we are going to see how to install Bellsoft Liberica JDK 17 on Red hat Enterprise Linux 9 for all users with JAVA_HOME Environment Variable

In this Example:


src ---- contains two java modules IPv4Validator and IPv4ValidatorClient Modules. Each Module must contain module-info.java which is mandatory.
classes ---- will store all the compiled class files of Java Modules.

Here IPv4Validator Module contains module-info.java which exports the com.javafrm package, so that other modules can access the package and com.javafrm package contains IPv4Validator.java .
Class name and Method should be public, then only you can access this class and required methods from other modules.

Next IPv4ValidatorClient Module contains contains module-info.java which requires (calls) IPv4Validator Module.
It contains org.javafrm package which contains IPv4ValidatorClient.java (Main class) and access the class and methods from IPv4Validator Module.

Example commands:

javac --module IP4ValidatorModule -d /opt/Java-Module-Programs/Modules/classes --module-source-path /opt/Java-Module-Programs/Modules/src

javac --module IP4ValidatorClientModule -d /opt/Java-Module-Programs/Modules/classes --module-source-path /opt/Java-Module-Programs/Modules/src

java --module-path /opt/Java-Module-Programs/Modules/classes --module IP4ValidatorClientModule/org.javafrm.IPv4ValidatorClient
