Java 之 橋接模式

public abstract class Abstraction {
	
	protected Implementor impl;

	public Abstraction(Implementor impl) {
		this.impl = impl;
	}

	// 示例方法
	public void operation() {
		impl.operationImpl();
	}
}


public abstract class Implementor {
	
	/**
     * 示例方法，實現抽象部分須要的某些具體功能
     */
    public abstract void operationImpl();
}

public class ConcreteImplementorA extends Implementor {

    @Override
    public void operationImpl() {
        //具體操做
    	System.out.println(ConcreteImplementorA.class);
    }

}

public class ConcreteImplementorB extends Implementor {

    @Override
    public void operationImpl() {
        //具體操做
    	System.out.println(ConcreteImplementorB.class);
    }

}

public class RefinedAbstraction extends Abstraction {
    
    public RefinedAbstraction(Implementor impl) {
        super(impl);
    }
    
    //其餘的操做方法
    public void otherOperation(){
        System.out.println(RefinedAbstraction.class);
    }
}

public class Client {
	
	public static void main(String[] args) {
		
		Implementor a = new ConcreteImplementorA();
		Abstraction ref = new RefinedAbstraction(a);
		ref.operation();
	}
}
