program code for counting the similarwrod in the sentences
public static int count(String word) { if (word == null || word.isEmpty()) { return 0; } int wordCount = 0; boolean isWord = false; int endOfLine = word.length() - 1; char[] characters = word.toCharArray(); for (int i = 0; i < characters.length; i++) { // if the char is a letter, word = true. if (Character.isLetter(characters[i]) && i != endOfLine) { isWord = true; // if char isn't a letter and there have been letters before, // counter goes up. } else if (!Character.isLetter(characters[i]) && isWord) { wordCount++; isWord = false; // last word of String; if it doesn't end with a non letter, it // wouldn't count without this. } else if (Character.isLetter(characters[i]) && i == endOfLine) { wordCount++; } } return wordCount; }
