toString() and other methods(if any).

Part 2. Create a child Class called “ElectricVehicle” strictly based on the UML.
Add comments stating where data fields, constructors, toString() and other methods(if
any).

Part 3. Write a main method inside Vehicle class, having the following:
a) Create a new instance of the “ElectricVehicle” class using the no-arg constructor
and assign it to the object reference of type “Vehicle” class.
b) Create a new instance of the “ElectricVehicle” class using the overloaded
constructor and assign it to the object reference of type “Vehicle” class.
c) Display the content of both the objects(using toString() method)

#name: String
#model: String
#year: int
#vehicleID: int
+Vehicle()
Vehicle
+Vehicle(name: String, model: String, year: int, vehicleID: int)
+setName(name: String): void
+getName(): String
+setModel(model: String): void
+getModel(): String
+set Year(year: int): void
+getYear(): int
+setVehicleID(vehicleID: int): void
+getVehicleID(): int
+getSeating Capacity(): int
