java-工厂

class Mouse{
    public void sayHi(){};
}

class DellMouse extends Mouse {
    @Override
    public void sayHi() {
        System.out.println("产品：戴尔鼠标");
    }
}
class HpMouse extends Mouse {
    @Override
    public void sayHi() {
        System.out.println("产品：惠普鼠标");
    }
}

class KeyBoard {
    public void kick(){};
}
class HpKeyBoard extends KeyBoard {
    @Override
    public void kick() {
        System.out.println("产品：惠普键盘");
    }
}
class DellKeyBoard extends KeyBoard {
    @Override
    public void kick() {
        System.out.println("产品：戴尔键盘");
    }
}
//总的工厂接口
interface PcFactory {
    public Mouse createMouse() ;
    public KeyBoard createKeyBoard() ;
}
class HpFactory implements PcFactory {
    @Override
    public Mouse createMouse() {
        return new HpMouse();
    }

    @Override
    public KeyBoard createKeyBoard() {
        return new HpKeyBoard();
    }
}
class DellFactory implements PcFactory {
    @Override
    public Mouse createMouse() {
        return new DellMouse();
    }
    @Override
    public KeyBoard createKeyBoard() {
        return new DellKeyBoard();
    }
}

//当需要增加一个华硕工厂时：
class AsusMouse extends Mouse {
    @Override
    public void sayHi() {
        System.out.println("产品：华硕鼠标");
    }
}
class AsusKeyBoard extends KeyBoard {
    @Override
    public void kick() {
        System.out.println("产品：华硕键盘");
    }
}
class AsusFactory implements PcFactory {
    @Override
    public Mouse createMouse() {
        return new AsusMouse();
    }
    @Override
    public KeyBoard createKeyBoard() {
        return new AsusKeyBoard();
    }
}

public class NormFactory {
    public static void main(String[] args) {
        PcFactory hpFact = new HpFactory();
        Mouse hpm = hpFact.createMouse();
        KeyBoard hpkbd = hpFact.createKeyBoard();
        
        PcFactory dellFact = new DellFactory();
        Mouse dellm = dellFact.createMouse();
        KeyBoard dellkbd = dellFact.createKeyBoard();
        
        hpm.sayHi();
        dellm.sayHi();
        
        hpkbd.kick();
        dellkbd.kick();
    }
}

打印结果如下：

产品：惠普鼠标
产品：戴尔鼠标
产品：惠普键盘
产品：戴尔键盘
