Setter and （不是 OR 或 VS ） 生成器模式

我有一种情况，我使用生成器模式来构造对象。最好的例子是披萨代码

public class Pizza {
  private int size;
  private boolean cheese;
  private boolean pepperoni;
  private boolean bacon;

  public static class Builder {
    //required
    private final int size;

    //optional
    private boolean cheese = false;
    private boolean pepperoni = false;
    private boolean bacon = false;

    public Builder(int size) {
      this.size = size;
    }

    public Builder cheese(boolean value) {
      cheese = value;
      return this;
    }

    public Builder pepperoni(boolean value) {
      pepperoni = value;
      return this;
    }

    public Builder bacon(boolean value) {
      bacon = value;
      return this;
    }

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

  private Pizza(Builder builder) {
    size = builder.size;
    cheese = builder.cheese;
    pepperoni = builder.pepperoni;
    bacon = builder.bacon;
  }
}

目前为止，一切都好。

现在让我们假设一个用例，我需要.这需要一个.我从未见过构建器模式与 setter 共存的单一示例，这让我怀疑我所做的是一种反模式。updatecheesesetter

二传手和建造者可以共存吗？
