this is the question

Java Programming Project 1 (2006-2007)

Sentence Statistics

For this project you are required to write a program which takes a sentence(i.e. string) as input , and prints out various statistics about the sentence. Sample output for the program will be shown below.

Example

Input sentence :

The first fir$t SP Project sp

Sentence Statistics

The Number of Valid Words5

The Longest WordProject

The Shortest WordSP

The Number of Times the longest word appeared (Ignoring Case)1

The Number of Times the shortest word appeared (Ignoring Case)2

The words counted by the program should only be valid words i.e. only those containing alphabetic characters.

NB: The project should be written using static methods. It is to be available for collection on the top level directory on your M drive by Friday Feb 2nd at 4pm and saved as prj10607.java

Note : Projects must be completed on your own, and plagiarism will result in all marks being deducted.

NB A written test based on the concepts required to solve this problem will be given immediately after this project is collected, if you do not submit both components i.e. project code and written tests you will NOT get a mark.
