CISC181 F2017 Lab5
- Make a new project with n = 5 (following these instructions)
- Name your main class "Lab5" (when creating a new module in the instructions above, in the Java class name field)
- Modify Lab5.java by adding your name and section number in a comment before the Lab5 class body.
In this lab you will analyze text files and get experience working with strings and characters by calculating some statistics about words in a file that you read. Your program will repeatedly prompt the user in the console to enter the name of a text file (relative to a base directory of your choosing) or 'q' to quit. If they do not want to quit, open the file with FileInputStream and read it with a Scanner, using this regular expression as your delimiter/word separator (see the slides for Oct. 11):
Be careful about cutting and pasting this into Android Studio. I have seen extra backslashes inserted automatically for several students, so make sure your delimiter string matches what you see here
After reading every word in the file, print the following information, each on its own line:
- Number of words
- Longest overall word. Note that if there are multiple words which "tie", the expected behavior is to output the first one found
- Longest capitalized word (first character is a capital letter)
- Word with most consonants. Treat 'y' as a consonant
- Alphabetically first word with 4 or more letters (treating upper-case and lower-case the same). Do not count words that start with a non-alphabetic character
- Alphabetically last word with 4 or more letters (treating upper-case and lower-case the same)
After printing this information, make sure to close the file, then prompt the user again until they want to quit.
All of this should be be in a public class WordStats. WordStats should have a constructor which takes the base directory string as its sole parameter, and handles the console input and looping itself. Note: FileInputStream's constructor wants the full-path name of the file. The user should only have to enter the simple file name. So the WordStats constructor parameter is the full path to the directory that the files live in, then concatenate that with the filename typed by the user
Please instantiate your WordStats class by creating an object in main(). You should test it with the following FOUR files:
Here is *some* of the expected output for the above files:
- getty.txt: 268 words, longest word = "proposition"
- doi.txt: 1325 words, longest word = "undistinguished"
- bts.txt: 14574 words, longest word = "obstreperousness"
- greatexp.txt: 186685 words, longest word = "architectooralooral"
