Problem: allPlural

Write a static method named allPlural that accepts an array of strings as a parameter and returns true only if
every string in the array is a plural word, and false otherwise. For this problem a plural word is defined as any
string that ends with the letter S, case-insensitively. The empty string "" is not considered a plural word, but the
single-letter string "s" or "S" is. Your method should return true if passed an empty array (one with 0 elements).
The table below shows calls to your method and the expected values returned:

{"She", "sells", "sea", "SHELLS"};
{"HANDS", "feet", "toes", "OxEn"};
{"shoes", "", "socks"};
Call and Value Returned
allPlural(a1) returns true
allPlural(a2) returns true
allPlural(a3) returns true
allPlural(a4) returns false
allPlural(a5) returns false
allPlural(a6) returns false
For full credit, your method should not modify the array's elements.
