Define an exception class called DiskDriveNotReady.

The class should have a constructor with no
parameters. If an exception is thrown with this zero-argument constructor, getMessage should
return “Disk Drive Not Ready!” The class should also have a constructor with a single parameter of
type String. If an exception is thrown with this constructor, then getMessage returns the value that
was used as an argument to the constructor.

```
public class DiskDriveNotReadyException extends Exception
{
public DiskDriveNotReadyException()
{
super("Disk Drive Not Ready!");
}

public DiskDriveNotReadyException(String message)
{
super(message);
}
}

```
