In this homework, you will write a generic class hierarchy for sets and maps for Java.
GTUSetInt is a Java interface with the following methods.
empty
Test whether container is empty
size
Return container size
max_size
Return maximum size
insert
Insert element, throws exception InvalidParameterException if the element is already in the set
intersection
The returned set is the intersection of this set and the given set.
erase
Erase element
clear
Clear all content
find
Get iterator to element
count
Count elements with a specific value
begin
Return iterator to beginning
end
Return iterator to end
The class GTUSet implements the GTUSetInt interface. It will keep its data using Java arrays.
Do not use any Java Collection classes. It implements the intersection method as follows:
intersection
GTUSetInt intersection(GTUSetInt)
The returned set is the intersection of this set and the given set.
The class GTUMap extends from GTUSet< javafx.util.Pair > and implements the
following extra method
at
Access element
V at(K k)
If k matches the key of an element in the set, the method returns a reference to its mapped value.
The class GTUIterator implements the following methods
boolean hasNext()
Returns true if this list iterator has more elements when traversing the list in the forward direction.
boolean hasPrevious()
Returns true if this list iterator has more elements when traversing the list in the reverse direction.
T next()
Returns the next element in the list and advances the cursor position.
T previous()
Returns the previous element in the list and moves the cursor position backwards.
Write your driver class to test the all the classes and all of their methods.
Notes
• Submit your nicely produced Javadoc documents with your homework.
• Do not forget to test the thrown exceptions
