An acronym is a word formed from the initial letters of words in a set phrase. Define a method named createAcronym that takes a string parameter and returns the acronym of the string parameter Append a period () after each letter in the acronym If a word begins with a lower case letter, don't include that letter in the acronym. Then write a main trogram that reads a phrase from input, calls createAcronym0 with the input phrase as argument, and outputs the returned acronym. Assume the input has at least one upper case letter. Ex. If the input is: Institute of Electrical and Electronics Engineers the output should be: I.E.E.E. Ex: if the input is: A. M. The letters ACHINERY in MACHINERY don't start a word, so those letters are omitted. The program must define and call a method: public static String createAcronym(String userPhrase) Hint: Refer to the ascii table to make sure a letter is upper case
