Recommended Book : Head First Design Pattern : http://amzn.to/2pY5xbR Prototype Design Pattern in Java This video contains both theory and practical session. Prototype design pattern belongs to Creational design pattern which belongs to Design Patterns in java. Prototype pattern refers to creating duplicate object while keeping performance in mind.
