For Exercises 22-25, use case-insensitive string comparisons. 22. Design and code a new method to be exported from ArrayStringLog called howMany, with the following signature: public int howMany (String element) The method returns an int value indicating how many times element occurs in the StringLog. 23. Design and code a new method to be exported from ArrayStringLog called uniqInsert, with the following signature: public boolean uniqInsert (String element) The method inserts element into the StringLog unless an identical string already exists in the StringLog, in which case it has no effect on the StringLog If it does insert the string, it returns true; otherwise, it returns false.
