## 5、代码实现 ##

> Brand

package oopdemo01.Design_pattern.bridge;
    
    // 品牌
    public interface Brand {
        void info();
    }

> Lenovo

package oopdemo01.Design_pattern.bridge;
    
    // 联想品牌
    public class Lenovo implements Brand {
        @Override
        public void info() {
            System.out.print("联想");
        }
    }

> Apple

package oopdemo01.Design_pattern.bridge;
    
    // 苹果品牌
    public class Apple implements Brand {
        @Override
        public void info() {
            System.out.print("苹果");
        }
    }

> Computer

package oopdemo01.Design_pattern.bridge;
    
    // 抽象的电脑类型类
    public abstract class Computer {
        // 组合，品牌——桥
        protected Brand brand;
    
        public Computer(Brand brand) {
            this.brand = brand;
        }
    
        public void info() {
            brand.info();   // 自带品牌
        }
    }
    
    
    class Desktop extends Computer {
    
        public Desktop(Brand brand) {
            super(brand);
        }
    
        @Override
        public void info() {
            super.info();
            System.out.println("台式机");
        }
    }
    
    class Laptop extends Computer {
    
        public Laptop(Brand brand) {
            super(brand);
        }
    
        @Override
        public void info() {
            super.info();
            System.out.println("笔记本");
        }
    }

> Test

package oopdemo01.Design_pattern.bridge;
    
    public class Test {
        public static void main(String[] args) {
            // 苹果笔记本
            Computer computer = new Laptop(new Apple());
            computer.info();
            // 联想台式机
            Computer computer1 = new Desktop(new Lenovo());
            computer1.info();
        }
    }

控制台输出结果：
