1. Create a Vehicle.java file. Implement the public Vehicle and Car classes in Vehicle.java, including all the variables and methods in the UMLS.
Vehicle
-
make: String
model: String
-year: int
+ Vehicle(String make, String, model, int, year)
+ getMake(): String
+ setMake(String make): void
+ getModel(): String
+ setModel(String model): void
+ getYear(): int
+ set Year(int year): void
+toString(): String
Car
- numDoors: int
+ numberOfCar: int
+ Car(String make, String, model, int, year, int numDoors)
+ getNumDoors(): int
+ setNumDoors (int num Doors): void
+ toString(): String
2. Create a CarTest.java file. Implement a public CarTest class with a main method. In the main method, create one Car object and print the object using
System.out.println(). Then, print the numberOfCar.
Your printing result must follow the example output:
make Toyota, model=Camry, year=2022 numDoors=4
1
Hint: You need to modify the toString methods in the Car class and Vehicle class!
