Class Diagram for the Jigsaw Puzzle
Explore how to design a jigsaw puzzle class diagram using object-oriented principles. Learn to define classes like Side, Piece, Puzzle, and PuzzleSolver, understand their relationships, and apply the Singleton pattern. This lesson prepares you to break down design requirements and implement structured solutions for complex OOD interview problems.
In this lesson, we’ll identify and design the classes, abstract classes, and interfaces based on the requirements we previously gathered from the interviewer in our jigsaw puzzle.
Components of a jigsaw puzzle
As mentioned, we should design the jigsaw puzzle using a bottom-up approach.
Side
The Side class represents the shape of our jigsaw piece and whether it contains an indentation, extrusion, or flat edge. The UML representation of the class is shown below:
Piece
The Piece class contains an array of sides of size four. It will also identify middle, corner, and edge pieces. The class representation of the Piece class is provided below: ...
