This coding problem (code is in java):

In this activity you will write and test a method that will autogenerate a review based on the review used in Activity 2. The method will autogenerate a review by replacing adjectives in the given review with randomly selected adjectives from a list.

1. Open your existing SimpleReview.txt file and annotate each adjective by adding a * at the beginning of the word. For example, the SimpleReview.txt from Activity 2 would be:

   This was a *terrible restaurant! The pizza crust was too *chewy, and I disliked the pasta. I would definitely not come back.

2. Write the method fakeReview. The method signature is given below.

   public static String fakeReview(String fileName)

   The parameter fileName should be the name of the annotated review (with * at the beginning of the adjectives). The fakeReview method should loop over the String containing the contents of the marked-up review to build and return a fake review. Remember, you are replacing only the adjectives with a random positive or negative adjective, which are marcated with a *.

   You are going to want to take advantage of the method randomPositiveAdj that returns a random word from the positiveAdjective.txt files. Feel free to add more adjectives to those files if you want those words to be used!

Example:

A test file containing:

The *quick *brown fox jumps over the *lazy dog.

may produce as its output:

The speedy smoky fox jumps over the fast dog.
