Java program question:

Write the function String PluralForm(String word) which takes a standard English word as a parameter and returns the plural form based on the following English rules. Punctuation should be preserved.

If the word ends in s, x, z, ch, or sh, add es to the end of the word.

If the word ends in o preceded by a consonant, add es to the end of the word.

If the word ends in y preceded by a consonant, replace the y with ies.

For all other cases, add an s to the end of the word.

Here are three examples of the output, software is very picky so it has to look exactly like this unfortunately:

This program converts an English word to its plural form. English word: toy Plural form: toys 

This program converts an English word to its plural form. English word: toy. Plural form: toys. 

This program converts an English word to its plural form. English word: toss Plural form: tosses 

Each word provided as input will comprise lowercase alphabetic characters. Also, each word may be terminated by one "normal" punctuation mark (i.e., any from ,.!?;). Input words will not contain any spaces, numeric digits, or other unspecified non-alphabetic characters.
