简化建造模式的Java代码

简化建造模式（Fluent Builder Pattern）是建造模式的一种变体，它主要用于创建复杂对象并提供一种更加简洁的语法。以下是一个简化建造模式的Java代码示例：

public class Car {
    private String make;
    private String model;
    private int year;
    private int mileage;

    public Car(String make, String model, int year, int mileage) {
        this.make = make;
        this.model = model;
        this.year = year;
        this.mileage = mileage;
    }

    public String getMake() {
        return make;
    }

    public String getModel() {
        return model;
    }

    public int getYear() {
        return year;
    }

    public int getMileage() {
        return mileage;
    }

    public static class Builder {
        private String make;
        private String model;
        private int year;
        private int mileage;

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

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

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

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

        public Car build() {
            return new Car(make, model, year, mileage);
        }
    }
}

使用简化建造模式创建对象的示例代码：

Car car = new Car.Builder()
        .make("Honda")
        .model("Civic")
        .year(2020)
        .mileage(1000)
        .build();

通过使用链式调用的方式，可以更加方便地创建对象，同时也避免了过多的构造函数重载。
