大话设计模式-桥接模式

UML

要实现的功能抽象类

public abstract class Implementor {
    public abstract void operation();
}

具体实现功能的两个类

public class ConcreteImplementorA extends Implementor {
    @Override
    public void operation() {
        System.out.println("具体实现类A的方法执行》》》");
    }
}

public class ConcreteImplementorB extends Implementor {
    @Override
    public void operation() {
        System.out.println("具体实现类B的方法执行》》》");
    }
}

对以上功能有需求的抽象类

public class Abstraction {
    protected Implementor implementor;

    public void setImplementor(Implementor implementor) {
        this.implementor = implementor;
    }

    public void operation() {
        implementor.operation();
    }
}

具体的产品

public class RefinedAbstraction extends Abstraction {
    @Override
    public void operation() {
        super.operation();
    }
}

测试类

public class Main {
    public static void main(String[] args) {
        Abstraction abstraction = new RefinedAbstraction();
        abstraction.setImplementor(new ConcreteImplementorA());
        abstraction.operation();

        abstraction.setImplementor(new ConcreteImplementorB());
        abstraction.operation();
        
    }
}

运行结果
