in Java

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' include that letter in the acronym. Then write a main program 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: Association for computing MNCHINERY the output should be: A,K. The letters ACHINERY in MACHINERY dont start a word, so those letters are omitted The program must define and call a method: public statie string ereateleronym(string userphrane) Hint: Refer to the ascil table to make sure a letter is upper case
