2. Листинги исходных текстов программ

3. Результаты роботы программ

4. UML диаграммы классов

5. HTML - документация

консольный приложение интерфейс программа

1. Задания

1.1 Исходное задание

1. Каждое задание оформить в виде:

1.1 Консольного приложения. Допускается использование диалоговых окон.

1.2 Оконного приложения на базе библиотеки Swing.

2. Реализовать чтение/запись результата в файл.

3. В каждом классе должны быть реализованы методы класса Object:

toString()

equals()

clone()

4. В каждом приложении должны быть продемонстрированы:

4.1 отношения:

Use-a

Has-a

Is-a

4.2 инкапсуляция, наследование, полиморфизм.

5. В каждом приложении должен быть создан массив и реализованы интерфейсы Comparator и Comparable.

С их помощью продемонстрировать методы класса Array (max, min, сортировка, бинарный поиск)

6. Для каждого swing приложения построена uml диаграмма классо

7. Для каждого приложения продемонстрировать самозапускаемый jar-file.

8. Для каждого задания разработать html документацию.

1.2 Индивидуальные задания

1. Ввести с консоли n целых чисел и поместить их в массив. Найти среди них указанные числа и вывести на консоль - наибольший общий делитель и наименьшее общее кратное этих чисел.

2. Выведите на экран "закрашенный" треугольник из звездочек ('*').

3. Создать класс "Компьютер" с полями "процессор" (String), "частота процессора" (double), "наличие WiFi" (bool). Наследовать его классом "Ноутбук" с дополнительными полями "диагональ" и "фирма-производитель".

4. Создать класс Department (отдел фирмы) с внутренним классом, с помощью объектов которого можно хранить информацию обо всех должностях отдела и обо всех сотрудниках когда-либо занимавших конкретную должность.

5. В задании требуется ввести последовательность строк из текстового потока и выполнить указанные действия - найти и вывести слова, для которых последняя буква одного слова совпадает с первой буквой следующего слова.

2. Листинги исходных текстов программ
