Java > AP-1 > wordsCount (CodingBat Solution)

Problem:

Given an array of strings, return the count of the number of strings with the given length.

wordsCount({"a", "bb", "b", "ccc"}, 1) → 2
wordsCount({"a", "bb", "b", "ccc"}, 3) → 1
wordsCount({"a", "bb", "b", "ccc"}, 4) → 0

Solution:

public int wordsCount(String[] words, int len) {
  int count = 0;  
  for (int i = 0; i < words.length; i++) {
    if (words[i].length() == len)
      count++;
  }
  return count;
}
