The length of that string actually be considered. We've started out by splitting the string and using a simple counter, followed by using the Collections helper class, and finally, using Regular Expressions. In real-world applications, the frequency() method can be used to analyze the frequency of words in a text. Then loop over all the words and first get the word as key from hashmap if it returns null then add the letter to hashmap with value 1 if same key comes in loop then get of hashmap will not return null it will return the old count which is 1 not increment it to My task is to get the word frequency of this file: test_words_file-1. g.
