示例：

public class BridgePatternDemo {

    public static void main(String[] args) {
        Somebody sb = new Xiaohong(new Banana());
        sb.eat();
        sb = new Liming(new Apple());
        sb.eat();
    }
}

interface Something {
    public String getName();
}

class Apple implements Something {

    public String getName() {
        return "apple";
    }

}

class Banana implements Something {

    public String getName() {
        return "banana";
    }

}

abstract class Somebody {
    protected Something something;

    public Somebody(Something something) {
        this.something = something;
    }

    abstract public void eat();
}

class Xiaohong extends Somebody {

    public Xiaohong(Something something) {
        super(something);
    }

    @Override
    public void eat() {
        System.out.println("Xiaohong eat " + something.getName());
    }

}

class Liming extends Somebody {

    public Liming(Something something) {
        super(something);
    }

    @Override
    public void eat() {
        System.out.println("Liming eat " + something.getName());
    }

}
