建造者模式(Builder Pattern)是一种创建型设计模式,用于将一个复杂对象的构建过程与其表示分离,以便可以使用相同的构建过程创建不同的表示。 结构 Builder(建造者)接口或抽象类: 定义了构建对象的各个步骤的方法。 ConcreteBuilder(具体建造者)类: 实现了 Builder 接口或继承 Builder 抽象类,负责实际
一、建造者模式简介(Brief Introduction) 建造者模式(Builder Pattern),将一个复杂对象的构建与它的表示分离,使的同样的构建过程可以创建不同的表示。 建造者模式的优点是:使得建造代码与表示代码分离,由于建造者隐藏了该产品是如何组装的,所以如要改变一个产品的内部表示,只需要再定义一个具体的建造者就可以了。 二...

Since Java‘record‘types are immutable by default, thebuilder patternis an excellent match for records. 1. Using Nested Builder The followingUserrecord contains a nestedBuilderobject that takes two mandatory arguments:idandname. The other two fields use the fluent API to set data. Finally, the...
I find it hard to use the above example in real-life programming and applications. The above process is very similar (not exactly) to theabstract factory pattern, where we find a factory (or builder) for a specific type of object, and then the factory gives us a concrete instance of tha...
