YOU WILL NEED TO IMPLEMENT THE FOLLOWING METHODS
================================================
CHECK THE ATTACHED FILE
The details of the specification are given in a comment
above the methods in the files. They currently just have
stub code.
DBLeafTreeNode.java
eval
DBBopTreeNode.java
eval (this is the most complicated thing you have to do
because there are so many binary operators and
types)
DBUopTreeNode.java
eval
BinarySearchTree
filteredSubset
filteredDelete
and the five aggregate operator methods if you do
the extra credit
Player.java
satisfies
evaluate
DB.java
the DB(Scanner) constructor
There are drivers and expected output for the drivers included in the zip file along with other classes and data needed.
