The removemethod replaces the removed entry with null becausea. the entry could potentially be scheduled for garbage collection b. the client expects a null return valuec. it is a fail-safe programming practiced. otherwise it could be considered a duplicate value19.When calling the removemethod with an argument if there are multiple entriesa. exactly which occurrence removed is unspecifiedb. only one occurrence is removed c. the first occurrence is removed d. all of the above

Suppose s, t, and w are strings that have already been created inside main. write a statement or statements, to be added to main, that will determine if the lengths of the three strings are in order by length, smallest to largest. that is, your code should determine if s is strictly shorter than t, and if t is strictly shorter than w. if these conditions hold your code should print (the boolean value) true. if not, your code should print false. (strictly means: no ties) example: if s, t, and w are "cat", "hats", and "skies" your code should print true - their lengths are 3-4-5; but if s, t, and w are "cats" "shirt", and "trust", then print false - their lengths are 4-5-5 enter your code in the box below
