Error handling
- Exception being defined as classes, they can have attributes/operations:
public class UnavailableException extends Exception {
private int limit;
public UnavailableException(int limit)
{ this.limit = limit; }
public int getLimit()
{ return limit; }
}
That can be used with the throw
statement:
throw new UnavailableException(book.getQuantity());
And the try_catch
:
try {
bookstore.buy("Core Java", 30);
} catch (UnavailableException e) {
System.out.println("Avalaible quantity: "+e.getLimit());
}
