ZeroException Task: -- Not needed
Exceptions are used to signal many types of problems in a program. We can write our own as well to describe specific exceptional conditions which may arise. The advantage of doing so is that when exceptions are thrown, we can use the type of the exception we've created to identify the problem from among a set of other possible problems.
Here we have invented the notion of a "zero exception," which we would use to indicate that something has a zero value when it shouldn't. So in our main task below, we have a class which can return values but is not allowed to return a zero (for whatever arbitrary reason). Thus, whenever it is supposed to return a value, and the value happens to be zero, it will throw a ZeroExceptioninstead. Do not confuse this with a divide by zero error. This class will be fairly simple: the only constructor we will expect to be able to call is a default constructor (truly, we hardly need to put anything in the class for it to work - an exception's job is only to report that an error happened, so it really only needs to exist to do its work).
ArrayManipulator Task - I only need this one:
Now we write a simple class which stores an array and allows us to set or get elements of the array. The getters include methods which manipulate values before returning them (i.e. multiply the number by a constant or divide the number by a constant). We will add one more constraint: the getters must never return a zero value. Instead, whenever we have a zero value, we would throw a zero exception instead.
The class should implement the following public methods:

IN JAVA: Write a class, ZeroException, which is an Exception, and is used to signal that something is zero when it shouldn't be. Write the class ArrayManipulator which creates an array and provides several methods to manipulate values taken from an array.

Array with Iterator. Java style
Implement an array data structure as a class JstyArray<E>
to support the Iterable interface such that the following code
works:
JstyArray<Integer> data;
data = new JstyArray<Integer>(10);
for (int i = 0; i < 10; ++i) {
data.set(i, new Integer(i) );
}
int sum = 0;
for ( int v : data ) {
if (v == null)
continue; // empty cell
sum += v;
}
The iterator provided by this class follows the behaviour of...

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...
