import java.util.Scanner;
public class MealEstablishmentDirectory {
public static void main (String[] args) {
Scanner scnr = new Scanner(System.in);
int newRating;
String newState;
MealEstablishment mealEstablishment1 = new MealEstablishment();
System.out.println("Default values: ");
mealEstablishment1.print();
newRating = scnr.nextInt();
newState = scnr.next();
mealEstablishment1.setRating(newRating);
mealEstablishment1.setState(newState);
System.out.println("After mutator methods: ");
mealEstablishment1.print();
}
}

Transcribed Image Text:In the class definition, initialize the private fields rating (integer) and state (string) with the default values 0 and "Undefined",
respectively.
Ex: If the input is 3 NV, then the output is:
Default values:
Rating: 0, State: Undefined
After mutator methods:
Rating: 3, State: NV
Note: The class's print() method is called before and after the input is passed to the setters.

The method determines if the String x is the exact reverse of the String y. If x is the exact reverse of y, the method returns true, otherwise, the method returns false. Other than uncommenting the code, do not modify the main method in Reverse.java. Sample runs provided below. Argument String x "ba" "desserts" "apple" "regal" "war" "pal" Argument String y "stressed" "apple" "lager" "raw" "slap" Return Value false true false true true falsearrow_forward
