java23中设计模式之桥接模式

-- 不用桥接模式的实现

package com.bjsxt.bridge;

public interface Computer {
    void sale();
}

class Desktop implements Computer {
    @Override
    public void sale() {
        System.out.println("销售台式机！");
    }
}

class Laptop implements Computer {
    @Override
    public void sale() {
        System.out.println("销售笔记本！");
    }
}
class Pad implements Computer {
    @Override
    public void sale() {
        System.out.println("销售平板电脑！");
    }
}

class LenovoDesktop extends Desktop {
    @Override
    public void sale() {
        System.out.println("销售联想台式机");
    }
}
class LenovoLaptop extends Laptop {
    @Override
    public void sale() {
        System.out.println("销售联想笔记本");
    }
}
class LenovoPad extends Pad {
    @Override
    public void sale() {
        System.out.println("销售联想平板电脑");
    }
}



class ShenzhouDesktop extends Desktop {
    @Override
    public void sale() {
        System.out.println("销售神舟台式机");
    }
}
class ShenzhouLaptop extends Laptop {
    @Override
    public void sale() {
        System.out.println("销售神舟笔记本");
    }
