Need help on java homework assignment, It says Create a class Vehicle. A Vehicle has a single instance variable of type String named "vehicleType" that describes the vehicle. It has an abstract method getTires that takes no parameters and returns an ArrayList object that describes each Tire of the vehicle. A Tire class has been provided. Vehicle has a single constructor that takes the vehicle type as a parameter. Create a class Bicycle that extends Vehicle that has two Tires, both of type "skinny". Bicycle should have a single default constructor. Create a class Dragster that extends Vehicle and has four Tires, two of type "slick" and two of type "medium". Dragster should have a single default constructor. Write a tester program to test Bicycle and Dragster objects. Use declarations such as Vehicle b = new Bicycle(); in your tester. Here is the code provided : public class Tire { private String size; public Tire(String siz) { size = siz; } public String getSize() { return size; } @Override public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; Tire other = (Tire) obj; if (size == null) { if (other.size != null) return false; } else if (!size.equals(other.size)) return false; return true; } }

Create a class Vehicle. A Vehicle has a single instance variable of type String named "vehicleType" that describes the vehicle. It has an abstract method getTires that takes no parameters and returns an ArrayList<Tire> object that describes each Tire of the vehicle. A Tire class has been provided. Vehicle has a single constructor that takes the vehicle type as a parameter.
Create a class Bicycle that extends Vehicle that has two Tires, both of type "skinny". Bicycle should have a single default constructor.
Create a class Dragster that extends Vehicle and has four Tires, two of type "slick" and two of type "medium". Dragster should have a single default constructor.
Write a tester program to test Bicycle and Dragster objects. Use declarations such as
Vehicle b = new Bicycle();
in your tester.
Here is the code provided :
public class Tire {
private String size;
public Tire(String siz) {
size = siz;
}
public String getSize() {
return size;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Tire other = (Tire) obj;
if (size == null) {
if (other.size != null)
return false;
} else if (!size.equals(other.size))
return false;
return true;
}
}
