Please write a java code

(put the secret file in a text file) the secret file is

Process a text file in order to decode a secret message. We will use the first letter of every 5^th token starting with the first word read in from a file to reveal the secret message.

1-Copy the file secret.txt. This file is only one line long. It contains 2 sentences.

2-Write a main method that will read the file secret.txt, separate it into word tokens.

3-You should process the tokens by taking the first letter of every fifth word, starting with the first word in the file. These letters should be converted to capitals, then be appended to a StringBuilder object to form a word which will be printed to the console to display the secret message.
