Small Word Filter With List
Geoffrey Challen // 2021.9.0
Write a method called smallWordFilter
that, given a non-null
String
containing words separated a single space
(" "), returns all the words in the original String
that are 3 characters or shorter in the same order in
which they appeared in the original String
, as a List<String>
.
For example, given the input "Xyz is the very best cat" you would return the List<String>
containing {"Xyz",
"is",
"the",
"cat"}
.
We have skipped both "very" and "best" because they are longer than 3 characters.
Note that you should not add any import
statements, since both java.util.List
and java.util.ArrayList
are
already available.
