00:00:01,080 --> 00:00:09,030
We can create chaos in Davos Square for example if we want to create a cost thought which has a property

2
00:00:09,030 --> 00:00:15,930
of weight and age and also a method park we can do it like this.

3
00:00:39,320 --> 00:00:42,420
And we can create a new object copy

4
00:00:48,730 --> 00:01:00,540
and then you can see if we use properly thought about it we'll have the results pop up that pop pop

00:01:00,610 --> 00:01:05,970
icon which means it also has the method.

6
00:01:06,410 --> 00:01:11,100
The puppy also has the method back then.

00:01:24,380 --> 00:01:27,320
which only has one method which is it

00:01:40,800 --> 00:01:51,590
if we want the thought inherit the animal cos we can use extend this word.

00:01:52,940 --> 00:02:04,670
Now if we try to use puppy dog it can see the puppy now has the it method and it also get the result
