See explaination
Step-by-step explanation:
import java.io.File;
import java.io.PrintWriter;
public class Question4 {
/*
* For this exercise you will be doing some basic operations to write to a
* file. You will be creating your very own Secrets of the Universe (TM)
*
* You can use the PrintWriter class to write to files (Chapter 11.4)
*
* Your code should perform the following actions:
*
* 1) Open/Create a file for writing at the following location:
* "files/question4/MySecretsOfTheUniverse.txt" If the file already exists
* you will want to overwrite its contents. 2) Add at least 3 of your own
* secrets of the universe to the file. Each secret should be on its own
* line. 3) Make sure to close your file so that the results are saved.
*
* Note: Your code should not throw any checked exceptions.Note: You will
* need to import some classes from the java.io package.
