Цель работы: Научиться писать программы с использованием классов и методов.
Задание: Создать классы, спецификации которых приведены ниже. Определить
конструкторы и методы setТип(), getТип(), toString(). Определить дополнительно методы в
классе, создающем массив объектов. Задать критерий выбора данных и вывести эти данные
на консоль. В каждом классе, обладающем информацией, должно быть объявлено несколько
конструкторов.
