Give the system control, not within your class. This is called control inversion.

Suppose we're going to design a

Girl

and a

Boy

Class

which

Girl

Yes

Kiss

Method

That

Girl

Want

Kiss

One

Boy

。

So, our problem is,

Girl

How to get to know this

Boy

？



In our China, the common mm and

Gg

There are several ways to recognize



1



Childhood



2



Friends and family introduction;



3



Parents arranged



So which one is the best?



Childhood:

Girl

I've known myself since I was a kid

Boy

。



public class Girl {

void Kiss () {

Boy boy = new Boy ();

}

}

However, it was created from the beginning

Boy
