This coding problem (code is in java):

Fake reviews can be slanted positive or negative. To create a positive review the program only needs to substitute positive adjectives for neutral or negative adjectives. To create a negative review the program would substitute only negative adjectives for neutral or positive adjectives.

In this activity youll write a new method modeled off the fakeReview method you wrote in Activity 3. The method will be redesigned so that it will make reviews stronger; that is, either more negative or more positive. Use the positiveOrNegative method provided in the Review class to write your new method, and name it after the type of fake review you plan on making.

Remember, we can determine how positive or negative an adjective is by using our sentimentVal method. If a word is above a specific threshold (0), that word is positive!

This is what there is so far in code:

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