Question

9. A concordance is an alphabetical word list for a passage of text. Each word in the concordance is mapped to an integer indicating the frequency of the word's occurrence. The constructor of Concordance has one String parameter that identifies the text file to be read. An incompleteConcordance class is below. public class Concordance public Concordance (String nameOfFileH concord new TreeMap<String, Integer 0 createConcordance (nameOfFile); //Constructor //nameOfFile the text file being read public void createConcordance (string filename)...) //Create a TreeMap of words mapped to their Integer frequencies public void printConcordance (... //Prints the alphabetized list of words paired with their frequencies private Map<String, Integer> concord; The method createConcordance will fill concord, a TreeMap of words mapped to their Integer frequencies. Complete the method createConcordance below. You may assume that all words in the passage are made up of lowercase letters. a. public void createConcordance (String filename) while (inFile.hasNext 0M//while more words to read String word- //read word from file // More code goes here
