An instance of the class ArrayBag has a fixed size, whereas an instance of ResizableArrayBag does not. Discuss and give at least two examples of situations where a bag would be appropriate if its size is: a. Fixed; b. Resizable.
Homework Answers
A) Fixed size: array.
Because arrays are fixed in size.
Once we create an array, there is no chance of increasing or decreasing size based on our requirement. Hence to use the arrays concept compulsory we should know the size in advance.
- Arrays can hold only homogeneous data.
- Arrays concept not built on some datastructure.i.e, there is no underlying datastructure for arrays.
B) Resizable : Any collection class.
We use collections concept here.
Because collections are growable in nature.
- Collections can hold homogenous as well as heterogenous data.
- Every collection class is implemented using a datstructure. Method support is there for any collection class
Some collection classes:
ArrayList,
LinkedList
Vector etc.,

Java Write an intersection method for the ResizableArrayBag class. The intersection of two bags is the overlapping content of the bags. Intersections are explained in more detail in Chapter 1, #6. An intersecion might contain duplicates. The method should not alter either bag. The current bag and the bag sent in as a parameter should be the same when the method ends. The method header is: public BagInterface<T> intersection(ResizableArrayBag <T> anotherBag) Example: bag1 contains (1, 2, 2, 3) bag2 contains...

Draw a UML class diagram that describes the following things. Use the standard UML stereotypes where appropriate. Show visibility, but do not show method signatures, attribute types, constructors, or destructors. Where appropriate distinguish between class and instance attributes and between class and instance methods. (Assume that all are instance attributes/methods unless otherwise indicated.) When an attribute is not another class in the diagram, show it inside the appropriate compartment. Otherwise show it as an aggregation relationship, with the appropriate role...
