Question

This is a program which will randomly generate sentences using five different arrays of strings. The arrays are as follows:

one array for nouns (must have at least 20 different words).
one array for adjectives (must have at least 20 different adjectives).
one array for verbs (must have at least 20 different verbs).
one array for prepositions (must have at least 20 different prepositions). one array for articles (can only have 2 "the" and "a").

Your application should have a method which accepts the five arrays as parameters and returns a randomly generated sentence using the strings from the given arrays. Your program should display seven different randomly generated strings every time the program is executed. NOTE: These strings should be different every time the program is executed.

A randomly generated string always has the following format:
<article> <adjective> <noun> <verb> <preposition> <article> <adjective> <noun>

NOTE: Please choose words in English, and keep your sentences school appropriate.
