`Java` нужно определить новый класс, который будет реализовывать интерфейс `Collection` или его подклассы, например, `List` или `Set`\r\nВ этом классе нужно реализовать все методы, объявленные в интерфейсе, включая методы добавления, удаления, поиска и перебора элементов коллекции.\r\n\r\nВот пример реализации простой коллекции на основе массива:\r\n\r\n```java\r\nimport java.util.*;\r\n\r\npublic class MyCollection<E> implements Collection<E> {\r\n\r\n private E[] elements;\r\n private int size = 0;\r\n\r\n public MyCollection() {\r\n elements = (E[]) new Object[10];\r\n }\r\n\r\n @Override\r\n public boolean add(E e) {\r\n if (size == elements.length) {\r\n elements = Arrays.copyOf(elements, size * 2);\r\n }\r\n elements[size++] = e;\r\n return true;\r\n }\r\n\r\n @Override\r\n public boolean remove(Object o) {\r\n for (int i = 0; i < size; i++) {\r\n if (Objects.equals(elements[i], o)) {\r\n System.arraycopy(elements, i + 1, elements, i, size - i - 1);\r\n elements[--size] = null;\r\n return true;\r\n }\r\n }\r\n return false;\r\n }\r\n\r\n @Override\r\n public int size() {\r\n return size;\r\n }\r\n\r\n @Override\r\n public boolean isEmpty() {\r\n return size == 0;\r\n }\r\n\r\n @Override\r\n public boolean contains(Object o) {\r\n for (int i = 0; i < size; i++) {\r\n if (Objects.equals(elements[i], o)) {\r\n return true;\r\n }\r\n }\r\n return false;\r\n }\r\n\r\n @Override\r\n public Iterator<E> iterator() {\r\n return new MyIterator();\r\n }\r\n\r\n @Override\r\n public void clear() {\r\n Arrays.fill(elements, null);\r\n size = 0;\r\n }\r\n\r\n private class MyIterator implements Iterator<E> {\r\n private int currentIndex = 0;\r\n\r\n @Override\r\n public boolean hasNext() {\r\n return currentIndex < size;\r\n }\r\n\r\n @Override\r\n public E next() {\r\n return elements[currentIndex++];\r\n }\r\n\r\n @Override\r\n public void remove() {\r\n MyCollection.this.remove(elements[currentIndex]);\r\n }\r\n }\r\n}\r\n```\r\nВ этом примере мы создаем новый класс `MyCollection`, который реализует интерфейс `Collection` с помощью дженериков. В этой коллекции мы используем массив `elements` для хранения элементов, и переменную `size` для отслеживания количества элементов в массиве.\r\n\r\nМы реализуем методы интерфейса `Collection`, включая методы добавления, удаления, поиска и перебора элементов
