Question

// An abstract Vehicle class

public abstract class Vehicle {
public Vehicle(String model, double rate) {
super();
this.model = model;
this.rate = rate;
}
private String model;
private double rate;
public double getRate() {
return rate;
}
public String getDescription() {
return model + " - Daily rate: $" + rate;
}
}

Answer 1

The question relates to an abstract Vehicle class in Java that cannot be instantiated directly but provides a common blueprint for subclass vehicle definitions.

Step-by-step explanation:

The question pertains to an abstract class in Java programming. An abstract class is a template definition from which other classes can be derived. In this case, the Vehicle class includes a constructor that initializes the model and rate of a vehicle. It also features methods getRate() and getDescription() which return the rental rate and a description of the vehicle, respectively. As an abstract class, it cannot be instantiated on its own and is meant to be a superclass for more specific vehicle classes.
