i dont understand what to do

The Rater class represents a rating system for a company. The company rated on a scale of 1-5. The toString representation changes based on how well rated the company is. Suppose we have a company called "Tina's Tires". . If its rating is less than two, toString would return "Not Recommended Company Tina's Tires" If its rating is over 3.5, toString would return "Gold Star Company Tina's Tires" Otherwise, toString would return "Well Rated Company Tina's Tires" . Remember, once a return statement is executed, the rest of the method is skipped. Therefore, if you return a String in an if statement, the remaining if statements will not be tested. The other method you need to fill in is setRating. The rating should only be changed if the new rating is 5 or less. After you fill in Rating, main should produce the following output. Note that main runs several test cases to check all of the conditions of the program! We need to make sure to test every line of code! Current Rating: 2.0 Well Rated Company Ir Cookery Current Rating: 4.5 Gold Star Company in Cookery Remember, once a return statement is executed, the rest of the me skipped.
