C 2.25 Redefine the Progression class, from Code Fragment 2.2, to be abstract and generic, producing a sequence of values of generic type T, and supporting a single constructor that accepts an initial value.

P 2.35 Write a Java program that inputs a list of words, separated by whitespace, and outputs how many times each word appears in the list. You need not worry about efficiency at this point, however, as this topic is something that will be addressed later in this book
