工厂模式例子（二）

抽象出产品

 

public abstract class AbstractProduct {
	private String motor;
	private int wheels;
	private Color color;
	public String getMotor() {
		return motor;
	}
	public void setMotor(String motor) {
		this.motor = motor;
	}
	public int getWheels() {
		return wheels;
	}
	public void setWheels(int wheels) {
		this.wheels = wheels;
	}
	public Color getColor() {
		return color;
	}
	public void setColor(Color color) {
		this.color = color;
	}
	public abstract void canLoad();
	
	public void print(){
		System.out.println(motor + "; wheels:" + wheels + "; color:" + color);
		canLoad();
	}
}

 

 具体的产品BUS

 

public class Bus extends AbstractProduct {
	public void canLoad() {
		System.out.println("Bus: can load at most 40 passengers");
	}
}

 具体的产品Car

 

public class Car extends AbstractProduct{
	public void canLoad() {
		System.out.println("Car: can load 4 passengers");
	}
}

 

 具体的产品Truck 

 

public class Truck extends AbstractProduct{
	public void canLoad() {
		System.out.println("Truck: can load much goods");
	}
}

 开始生产产品

 

public class BuilderTest {
	public static void main(String[] a){
		//创造不同的Builder
		Builder builder1 = new CarBuilder();
		Builder builder2 = new BusBuilder();
		Builder builder3 = new TruckBuilder();
		
		//Director使用不同的Builder，最终得到不同的产品
		Director director = new Director(builder3);
		director.construct();
		AbstractProduct product = builder3.getProduct();
		product.print();
	}
}
