Улучшения в Java 7 (multiple exceptions)

Перепиши реализации методов класса Solution.
Используй нововведения (multiple exceptions), касающиеся обработки исключений, которые были добавлены в Java 7.


Требования:
1.	В конструкторе класса Solution в одном catch блоке должны быть обработаны исключения WrongDataException и ConnectionException.
2.	В методе write в одном catch блоке должны быть обработаны исключения WrongDataException и ConnectionException.
3.	В методе read в одном catch блоке должны быть обработаны исключения WrongDataException и ConnectionException.
4.	В методе disconnect в одном catch блоке должны быть обработаны исключения WrongDataException и ConnectionException.
