Need help on a Java question to count the words.

I almost finished this problem. But I cannot finish pass three tests.

The following is the method I implemented:

getWords method: split words from given text, the words are separated by ' ' and '\t'.

isMatch method: determine if the word satisfies rules in the problem, like not null, at least three characters and etc. Details can see in my code.

countWord method: count how many words extracted in getWords which also satisfy the rules define by isMatch.

Following is my code:

There are three tests I cannot pass, which I don't know how to deal with it.

@Test void should_trim_start_and_end_whitespace_characters() { assertIterableEquals(Collections.singletonList("word"), WordsCounter.getWords(" word\t\t")); assertIterableEquals(Collections.singletonList("word\f"), WordsCounter.getWords(" word\f\t")); assertIterableEquals(Arrays.asList("word", "count"), WordsCounter.getWords(" word\t\tcount ")); }

@Test void should_not_match_for_special_letter_character() { assertFalse(WordsCounter.isMatch((char)255 + "ord2")); } @Test void should_not_match_other_digits_character() { assertFalse(WordsCounter.isMatch("word\u0660")); }

I think you should preserve much of my code cause there're many other tests I already passed but I did not put them here.

Thank you very much.
