Help with Java program using JDK 17

A Framework has been provided (Starting code). Using JDK 17 is recommended PLS THIS ONE IS IMPORTANT: The testing of code will be carried out in a Linux environment. The environment will not be running Windows, and neither IntelliJ nor Eclipse (or any other IDE) will be involved. OpenJDK 17 will be used to compile and execute your code and tests. It is critical that your code compiles. Your code folder should have the following internal structure: src/ folders (packages) and .java files for classes described in the Javadoc test/ folders (packages) and .java files for the JUnit test classes Pls read the Description PDF and follow its instruction and use the Code specification document (Javadoc) ie. "[login to view URL]". You must implement the classes and methods exactly as described in this specification. If your code does not conform to the specification it will fail the automatic check. If the html file in Javadoc required log-in pls contact me.
