Hi:

I have written a simple library for an assignment called GenericSet. It extends TreeSet, and its meant to be able to contain unique objects of the same type.And all the methods are static as required in the question.

Now when i run the code using a test class...i get this error:

incompatible types; no instance(s) of type variable(s) T exist so that com.GenericSet.GenericSet conforms to com.GenericSet.GenericSet<java.lang.Double>
found : <T>com.GenericSet.GenericSet
required: com.GenericSet.GenericSet<java.lang.Double>
GenericSet<Double> set2=GenericSet.initialize();

i dont know how to solve it. The code for my Library and the test clas sis below:

GenericSet Library




Now this is my test class



Please please can someone tell me where i went wrong?

Thanks
