What is the Prototype Design Pattern in Java?

Can you explain the Prototype Design Pattern in Java?

Sure! The Prototype Design Pattern is a creational pattern that allows you to create new objects by copying an existing object, known as the prototype.

How does it differ from other design patterns?

Unlike other creational patterns like Singleton or Factory, the Prototype pattern focuses on cloning existing objects rather than creating new instances from scratch.

Can you give me a code example?

Certainly! Here's a simple example:

public abstract class Prototype {
    public abstract Prototype clone();
}

public class ConcretePrototype extends Prototype {
    private String field;

    public ConcretePrototype(String field) {
        this.field = field;
    }

    @Override
    public Prototype clone() {
        return new ConcretePrototype(this.field);
    }
}

What are the advantages of using the Prototype pattern?

The advantages include reduced overhead of object creation, the ability to create complex objects easily, and promoting loose coupling.
