    You should override all the class's toString() methods to return the String you want to see when the linked list is printed.

    You should add ID Strings in all the println()s so you can easily recognize what was printed. For example:
    Java Code:
    System.out.println("an ID "+ THEVARIABLENAMEHERE);
    Change "an ID" to be the message you want to see, for example the name of the variable.
    I know this doesn't work, but would I do something like this in the main?

    Java Code:
    Arrays.toString(list);

    Default Re: LinkedList question

    Did you add the toString() method to all the classes? Adding that will change what is printed.

    See the Object class's API for what the method's signature looks like. Be sure to put an @Override notation immediately before the method definition.
    If you don't understand my response, don't ignore it, ask a question.
