Retrieve the average number of vowels per word in a .txt input
Given the supplied text file (INPUT.TXT), write a Java program that loads all words and determines the average number of vowels per word grouped by: set of vowels present in a word and length of the word. Result should be written to the output file (OUTPUT.TXT).
Assumptions:
-
Capital and lower case letter should be treated as the same. -
Input contains only English words and punctuation, words are separated by at least one whitespace character. -
Input is small enough to fit in memory.
INPUT:
Platon made bamboo boats.
OUTPUT:
({a, o}, 6) -> 2.5
({a, o}, 5) -> 2.0
({a, e}, 4) -> 2.0
5 vowels in 2 words ("Platon", "bamboo") = 5/2 = 2.5
2 vowels in 1 word ("boats") = 2/1 = 2.0
2 vowels in 1 word ("made") = 2/1 = 2.0
Initialize a HashMap:
- key: ({vowels}, wordLength)
- value: (wordCounter, vowelsCounter, averageNumberVowels)
For each word in the list:
- Sanitize word
- Get vowels from word
- Generate key
- Generate value:
- Increment wordCounter
- Increment vowelCounter
- Calculate average (vowelCounter / wordCounter)
- Insert key,value in the HashMap
