老師在上面說 如果實(shí)現(xiàn)了序列化接口那么其父類的則看不見父類的構(gòu)造方法被調(diào)用。

如果是這樣的話，最后的輸出結(jié)果難道不應(yīng)該是

bar1...

bar2...

嗎？為什么我的結(jié)果確實(shí)連父類的構(gòu)造方法也調(diào)用了？

//		oos.writeObject(foo2);
//		oos.flush();
//		oos.close();

//		//反序列化是否遞歸調(diào)用父類的構(gòu)造函數(shù)
//		ObjectInputStream?ois=new?ObjectInputStream(

		ObjectOutputStream?oos=new?ObjectOutputStream(
				new?FileOutputStream("exer/obj.dat"));
		Bar2?bar2=new?Bar2();
		oos.writeObject(bar2);
		oos.flush();
		oos.close();
		
		//反序列化是否遞歸調(diào)用父類的構(gòu)造函數(shù)
		
		ObjectInputStream?ois=new?ObjectInputStream(

		Bar2?bar21=(Bar2)ois.readObject();
		System.out.println(bar21);
		ois.close();
