What is the Builder Pattern in Java?

Can you explain the Builder Pattern in Java?

Sure! The Builder Pattern is a design pattern that allows for the step-by-step construction of complex objects.

What are the main benefits of using the Builder Pattern?

The main benefits include improved readability, easier object creation, and the ability to create immutable objects.

Can you provide a simple code example?

Absolutely! Here's a basic example:

class House {
    private final int rooms;
    private final String color;

    private House(Builder builder) {
        this.rooms = builder.rooms;
        this.color = builder.color;
    }

    public static class Builder {
        private int rooms;
        private String color;

        public Builder setRooms(int rooms) {
            this.rooms = rooms;
            return this;
        }

        public Builder setColor(String color) {
            this.color = color;
            return this;
        }

        public House build() {
            return new House(this);
        }
    }
}

You can create a House object like this:

House house = new House.Builder().setRooms(3).setColor("Blue").build();

Are there any drawbacks to using the Builder Pattern?

Yes, it can introduce additional complexity and may require more code compared to simpler object creation methods.
