Explanation:
Car.java
//class Car
public class Car {
//private variable declarations
private int year;
private double price;
//getYear method
public int getYear() {
return year;
}
//setYear method
public void setYear(int year) throws CarException {
//check for the year is in the given range
if(year>=1970&&year<=2011)
this.year = year;
//else throw an exception of type CarException
else
throw new CarException("Invalid Year");
}
//getPrice method
public double getPrice() {
return price;
}
//setPrice method

}
//default constructor to set default values

}
//copy constructor
public Car(Car c){
this.year=c.year;

}
//toString method in the given format
public String toString() {
return "[Year:" + year + ",Price:" + (int)price + "]";
}
//finalize method
