Description:
Create a package called booksthat includes 3 files: Book.java, BookApp.java, and books.csv (provided).
Class Book represents Pulitzer prize winning books that have a title, an author and a year, when they won the award.
Implement the class Book exactly as specified in the UML diagram below.
You are allowed to create private methods to structure your code, but fields, constructors, and public methods must not be changed nor added or removed.
Notice that class Book implements the interface Comparable<T>. The method specified in the interface is not listed in the UML class diagram of class Book. However, the fact that Book implements Comparable<T> implies that the interface method needs to be implemented.
The interface Comparable<T> implements the natural order. In case of class Book it should sort by title.
Also notice that class Book is immutable. It has getters but no setters.
Method toString:
The toString method should return a string of the following form: name by author ( year )
Make sure to include the @Override annotation
Method getList:
Note that the method getList is underlined. Underlining a method in a UML class diagrams indicates that the method is static.
The method getList should readin the data from the csv file book.csv. If a line doesn’t follow the pattern title,author,year then a message should be written to the standard error stream (see sample output) The program should continue reading in the next line. NO exception should be thrown .
Please note that the sample output is only provided to help clarify the instructions. The program still needs to fulfill all the requirement when I test it with another csv file (e.g. where all lines are correct or other lines have an issue)
Write a test client called BookApp.java
-
It should read in the data from the file book.csv. Two lines have an issue. Treat them as described above.
-
Print the number of books that were read in.
Make sure to determine the number of books at run time. I will test your code with a different csv file.
-
Sort the list in natural order and print the list
-
Sort the books in the list in reverse order using a Comparator<T>that is provided in class Collections
Problem reading in “No Pulitzer prize for fiction was awarded in 2012” Problem reading in “The Brief, Wondrous Life of Oscar Wao,Junot Diaz,2008” Number of books read in: 14
