Question

As provided, the main() routine does not compile because the drive() method might throw an exception. Place the drive() command into a try block and write the code that catches the exception if it is thrown. The class files should compile and the main program should now run.
Place the code that would provide the error message “Can’t Drive a Car with No Gas!!” when the exception is thrown.
Add the code that would print the message “Car is Ready” if the exception is not thrown.

Class car

public class Car { public Car(String name, double level) { carID = name; gasLevel = level; } public String getName() { return carID; } public void drive(double miles) throws GasException { if ((miles > 0) && (gasLevel<0)) throw new GasException(); } // Data private String carID; private double gasLevel; }

Main.java

public class CarMain { public static void main(String[] args) { Car c1 = new Car("My Chevy", -100); c1.drive (50); } }

GasException.java

public class GasException extends Exception{ private static final long serialVersionUID = 1L; public GasException(){ super(); } }
