package com.tontisa.Testfactory;


//工厂接口

interface Car {
public void run();


public void stop();

}


//工厂的实现

public class Benz implements Car {


@Override
public void run() {
System.out.println("Benz开始启动了。。。。。");
}


@Override
public void stop() {
System.out.println("Benz停车了。。。。。");
}


}

public class Ford implements Car {


@Override
public void run() {
System.out.println("Ford开始启动了。。。");
}


@Override
public void stop() {
System.out.println("Ford停车了。。。。");
}


}



//工厂

public class Factory {


public static Car getCarInstance(String type) {
Car c = null;
try {
c = (Car) Class.forName("com.tontisa.Testfactory." + type).newInstance();
} catch (InstantiationException e) {
// TODO Auto-generated catch block

} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}


return c;
}
}

//调用地点


public class FactoryImpl {


public static void main(String[] args) {
Car c = Factory.getCarInstance("Ford");// ****这里调用具体的实现类
if (c != null) {
c.run();
c.stop();
} else {
System.out.println("造不了这种汽车。。。");
}


}
