Record Set pattern

Description:

Implement the Record Set design pattern to facilitate operations on a collection of records, akin to a database result set. This pattern allows for easy manipulation, retrieval, and iteration of records within a software system. The Record Set pattern is particularly useful for applications that require interaction with a large volume of records or need to provide an abstraction layer for database operations.

Main Elements of the Pattern:

• RecordSet Interface: Defines methods for manipulating and accessing records, such as querying, updating, and iterating over the collection.
• ConcreteRecordSet: Implements the RecordSet interface, providing concrete behavior for the methods defined.
• Record: Represents a single entry within the RecordSet, encapsulating the data and behaviors specific to a record.
• Cursor/Iterator: Facilitates traversal over the records in the RecordSet, allowing clients to navigate through the records efficiently.
• Operations: Methods for filtering, sorting, and aggregating records within the RecordSet.

Acceptance Criteria:

1. Implement a RecordSet interface with methods for common operations such as querying, updating, and iterating records.
2. Create a ConcreteRecordSet class that provides the implementation for the RecordSet interface.
3. Include unit tests to validate the functionality of the RecordSet implementation, ensuring that all methods behave as expected.

No source file, entry point, or test path is specified. Start by reviewing the Java Design Patterns contribution guidelines and the linked Record Set references, then determine how the requested RecordSet, ConcreteRecordSet, Record, and cursor or iterator fit the repository; done means the interfaces, implementation, and unit tests satisfy all three acceptance criteria.
