java建造者模式代码

建造者模式是一种创建型设计模式，它允许您创建不同类型的对象，同时避免构造函数污染。以下是 Java 中的建造者模式示例代码：

public class Product {
private String property1;
private String property2;
private String property3;

public Product(ProductBuilder builder) {
this.property1 = builder.property1;
this.property2 = builder.property2;
this.property3 = builder.property3;
}

public String getProperty1() {
return property1;
}

public String getProperty2() {
return property2;
}

public String getProperty3() {
return property3;
}

public static class ProductBuilder {
private String property1;
private String property2;
private String property3;

public ProductBuilder() {}

public ProductBuilder withProperty1(String property1) {
this.property1 = property1;
return this;
}

public ProductBuilder withProperty2(String property2) {
this.property2 = property2;
return this;
}

public ProductBuilder withProperty3(String property3) {
this.property3 = property3;
return this;
}

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

使用建造者模式创建对象的示例代码：

Product product = new Product.ProductBuilder()
.withProperty1("value1")
.withProperty2("value2")
.withProperty3("value3")
.build();
