Create a class called Sets for positive integers that will have the following functions:

addElement , will take a positive integer and add it to the set

getElement, will take a position number and return the element at the position (return -1 if bad position)

getSize, return the size of the set

isSubset, takes a sets object (call it b) and see if the current set (call it a) is a subset of b. If so, return a Boolean true, else return a Boolean false

isProper, takes a sets object (call it b) and see if the current set (call it a) is a proper subset of b. Note, use the isSubset function first then see if b has at least one more element than a

printOrderedPairs, takes a sets object (call it b) and takes the current set (call it a) and prints the ordered pairs of of A X B

Have main create two objects: setA and setB.

Input the values into setA (end with a 0 or negative) and input the values into setB (end with 0 or negative).

Print the ordered pairs using printOrderedPairs.

Print if setA is a subset of setB.

Then print if setA is a proper subset of setB.
