    Re: need help constructing get method

    I need the get method to receive a string value, check if it exists in the tree, and return either the object/key that the string corresponds to or a null value if it does not exist. I know I need...

    need help constructing get method

    This is one of three trees I am using to parse text and print out every unique word, the line numbers it appears on, and the number of times it appears. I have already used a hash and tree map and...

    Re: Presumably simple fix sets/maps

    There is currently no point in my code that saves an item for checking. How would I save the value itr.next() prints? I cannot make some integer variable and just assign it to equal itr.next() as...

    Re: Presumably simple fix sets/maps

    So you are saying what needs to be inserted into the linked list needs to be a string including the line number instead of an integer? ...Or are we just talking about output for debugging purposes?

    Re: Presumably simple fix sets/maps

    What is your suggestion? I must be missing the point. I do not see how my printout is different from yours except for the concatenation of "wordMap=" and "pE entry=".

    wordmap is line 2. the values for each entry are above their respective entries.

  14. Re: Could anyone please advise me on this unfinished code? THANK YOU! (I know there are errors)

    Well one problem I can see is that you are scanning for the name and score after the if-statements that test them. The if-statements would have already ran when the variables are filled with the...

    Re: Presumably simple fix sets/maps

    Forgive my ignorance, but where? There is a hasNext() call on line 49 when it runs through the iterator to call the printEntry method.

    So get rid of the elseif statement and put something in around the while loop at the bottom of the main class?
