Csc 1351-03 Spring 2017, Lab 8: Project Set create a project named set that illustrates the use of generic classes and generic methods mplementing a Generic Set Class DEFINITION 1. Generics is a way of defining classes, interfaces and methods by using type pa rameters to represent types. A more technical term for generics is parametric polymorphism A generic method, interface or class is fully specified at run time. In Java, a generic type can only be specialized using an object type. Every primitive type in Java has an associated object type (a wrapper class DEFINITION 2. A set is a finite or infinite collection of objects in which order has no significance and multiplicity is generally also ignored. Members of a set are often referred to as elements and the notation r E A is used to denote that r s an element of a set A. A set is usually denoted as a list of elements. For example, 12. 3. 4, 5. G is a set that contains five elements. In today's lab, you will implement a generic class, the set T class. The class will be generic but its methods will not be generic. Some methods will use the formal type parameter of the class. In this lab, we introduce a basic software engineering concept called composition one object is composed of another. A set is composed of a list We will use the Java API ArrayList class Basic Set Operations DEFINITION 3. The cardinality of a set is the number of elements that the set contains. For example, the cardinality of A f2.3, 4, 5, 6h, denoted A is 5 DEFINITION 4. The intersection of two sets A and B is the set of elements common to A and B. This is written An B.and is pronounced "intersection" or "cap DEFINITION 5. The union of two sets A and B is the set obtained by combining the members of each without allowing multiplicity. This is written A u B, and is pronounced "union" or "cup DEFINITION 6. The difference of sets A and B denoted A-B, is the set of elements belonging to set A but not B
