I am creating a program that uses a Search Binary Tree to keep track of students that get added and deleted from a list. The program reads a text file that contains certain a command (add, delete, calculate average,etc) followed by the student name, age, and gender. For example, the first line of the text file would be: E Jake 14 M. E would stand for enroll(add).

I'm having issues both conceptually and coding wise.

I have a queue class, a queueLL class that implements the queue class, I have a camper class that returns name, age, and gender, and compares each student name, and lastly I have my search binary tree class.

The issue is in the main class:


I don't think my implementation is correct and I am hitting a wall in terms of trying to finish the code. I get errors of trying pass the file argument in Camper



The values define were 3 strings in my Camper Class file (name, age, gender). Any Help would be appreciated!

Edit Code for Camper:

Not sure. But I can see the keyword static appearing frequently. Why? I always work on the assumption that any sue of static must have a good explanation, otherwise it is a mistake. You should move nearly all that code out of the main method into instance methods. Your use of static would imply that you only have one camp anywhere, but instance methods would permit multiple camps.
Why have you used on demand import for java.io and imported one class from java.util by name. Prefer single imports to on demand. I can see you opening Scanners but I can't see you closing them.
Why have you made your compareTo method so complicated, when you are only comparing the String field? You can simplify that no end. What happens if you get two people with the same name and different ages?

You cannot pass a file to the camper constructor because you specified three arguments. You have to read name age gender from your file and pass those individually.
