Your task is to implement FIFOIntQueue and FIFOIntQueue that has to be implemented with the usage of IntQueueNode class and has to satisfy the set of methods defined in AbstractIntQueue class ( so definitely this time you cannot use lists and arrays for your implementation).

You can add new classes, new constructors, fields, methods to existing classes. Your solution has to pass some basic tests from the FIFOTest and LIFOTest test definitions. You can run them from console with gradlew wrapper

./gradlew test

or using GUI of your IDE as you did during some previous task.

Your task is also to add at least two mentioned small tests of your implementation in FIFOTest and LIFOTest in places marked with TODO.

The last part is to work a little with the documentation of your classes - let's notice that provided documentation in AbstractIntQueue e.g. for offer says nothing about the order of adding the element to the queue - your task is to provide some more detailed documentation if it's not obvious how the method would behave (it'll automatically overwrite the documentation from the parent class).

In your code you can also add new methods to different queue classes as you did in your queue diagram model - name them property, and then they won't even need any documentation 😉

You have time until the end of 09.04.2022

1. If you want to run your code, and you don't use the IDE that provides magic green buttons for running main function, you can run it with

   ./gradlew shadowJar
   java -jar ./build/libs/oop-2022-all.jar

   which will first package all your classes and dependencies to oop-2022-all.jar file and then run it on JVM.

2. Integer is an immutable class, so you don't have to worry about copying values received in arguments that will be stored in your queue.

3. Remember about cleaning your code and revisiting visibility modifiers before sending solution as now you can loose points for bad approach here.

4. Write any time with any questions about the task if you want.
