Need help removing item from ArrayList

Im attempting to remove an object form an array list but if fails everytime. Im using a function to add and a seperate one to remove. The add function is working but the remove is not. I cant see where it is going wrong and failing.

public void unregister( Basics classToRemove){
 if(checkIsRegistered(classToRemove)){
    getClassList().remove(classToRemove);
    System.out.println(getClassList().remove(classToRemove));
    System.out.println("You have unregistered from " + classToRemove.className + " class.");
            setTotalTuition();
        } else{
            System.out.println("\nYou are not currently registered for " + classToRemove.className + " class.\n");
        }
}

public void register(Basics classToAdd){
  if(!checkIsRegistered(classToAdd)){
    getClassList().add(classToAdd);
    System.out.println("You have registered for " + classToAdd.className + " class.");
    setTotalTuition();
    }else{
        System.out.println("\nYou are already registered for " + classToAdd.className + " class.\n");
    }
}

I have attempted using this.arrayList to remove the object and using getters to get the object and remove it.

You can not just print a class-object with System.out.printline. I assume you want to print the attributes of the class, however you are printing the memory address of the object.

Additionally, this doesn't make sense to me:

getClassList().remove(classToRemove);
System.out.println(getClassList().remove(classToRemove));

You can't access and print an Object you just removed.

If this is not helpful, consider providing a minimal example and explaining what exactly is not working.
