学习笔记----------abstractfactory抽象工厂

一般产生多个实例

模拟代码：

abstractfactory.java

package abstractfactory;
public abstract class AbstractFactory {
public abstract Vehicle createVehicle();
public abstract Weapon createWeapon();
public abstract Food createFood();

}

DefaultFactory.java 实现AbstractFactory接口

package abstractfactory;
public class DefaultFactory extends AbstractFactory{
@Override
public Food createFood() {
// TODO Auto-generated method stub
return new Apple();
}
@Override
public Vehicle createVehicle() {
// TODO Auto-generated method stub
return new Car();
}
@Override
public Weapon createWeapon() {
// TODO Auto-generated method stub
return new AK47();
}

}

MagicFactory.java 实现AbstractFactory接口

package abstractfactory;
public class MagicFactory extends AbstractFactory {
@Override
public Food createFood() {
// TODO Auto-generated method stub
return new MushRoom();
}
@Override
public Vehicle createVehicle() {
// TODO Auto-generated method stub
return new Broom();
}
@Override
public Weapon createWeapon() {
// TODO Auto-generated method stub
return new MagicStick();
}

}

Food.java

package abstractfactory;
public abstract class Food {
public abstract void printName();
}

Vehicle.java

package abstractfactory;
public abstract class Vehicle {
public abstract void run();
}

Weapon.java

package abstractfactory;
public abstract class Weapon {
public abstract void shoot();
}

Apple.java

package abstractfactory;
public class Apple extends Food {
public void printName() {
System.out.println("apple");
}
}

Car.java

package abstractfactory;

public class Car extends Vehicle {

public void run() {
System.out.println("ð���̱�����car.......");
}
}

AK47.java

package abstractfactory;
public class AK47 extends Weapon{
public void shoot() {
System.out.println("������...");
}
}

Test.java 这里DefaultFactory f = new DefaultFactory();中的new DefaultFactory();换成new MagicFactory（）就可以换掉一套的行为v.run();，w.shoot();，a.printName();， new MagicFactory（）为自定义的（你自己仿照DefaultFactory工厂写吧）

package abstractfactory;
public class Test {
public static void main(String[] args) {
//DefaultFactory f = new DefaultFactory();
AbstractFactory f = new DefaultFactory();
Vehicle v = f.createVehicle();
v.run();
Weapon w = f.createWeapon();
w.shoot();
Food a = f.createFood();
a.printName();
}
}
