I hope you enjoyed this section and that you were able to complete this assignment based on the previous

2
00:00:11,760 --> 00:00:19,800
lectures and this assignment, we wanted to create an enum called Shape and provide the values of Triangle,

3
00:00:19,800 --> 00:00:22,650
Square, Pentagon and Octagon.

4
00:00:23,640 --> 00:00:30,150
Then we need to create a method for this enum that returns the number of corners each shape has based

5
00:00:30,150 --> 00:00:31,830
on the type of shape.

6
00:00:31,860 --> 00:00:38,220
So, for example, if we have a triangle, we will return three, and then if we're square, we will

7
00:00:38,220 --> 00:00:39,450
return four.

8
00:00:40,500 --> 00:00:46,760
So the first thing that we need to do is create an enum called Shape, and we need to give it some variance.

9
00:00:46,770 --> 00:00:55,020
So we are going to give it Triangle, Square, Pentagon to go on.

10
00:00:57,210 --> 00:01:01,530
Now we need to implement our method on the Shape Enum.

11
00:01:03,110 --> 00:01:07,760
And we're going to call it corners and we need to have a reference to our self.

12
00:01:08,660 --> 00:01:14,000
And then we know that we want to return how many corners we have, so we're going to return an eight.

13
00:01:15,110 --> 00:01:24,650
So now we are going to do a match on ourself and if we are a triangle we want to return three.

14
00:01:25,670 --> 00:01:36,440
If we are a square, we want to return four, and if we are a Pentagon, we want to return five.

15
00:01:37,130 --> 00:01:38,780
And then if we're an octagon.

16
00:01:38,780 --> 00:01:44,150
And since that's our only other case, we can use the underscore as our catchall.

17
00:01:44,900 --> 00:01:48,230
Then we want to return eight in that case.

18
00:01:49,870 --> 00:01:57,100
So now we will say let shape equals shape triangle and we want to verify our results.

19
00:01:57,100 --> 00:01:59,830
So we will just print them out.

20
00:02:00,670 --> 00:02:04,060
So we will say shape dot corners.

21
00:02:04,750 --> 00:02:09,280
And now we can run our code and we see that we have three.

22
00:02:09,290 --> 00:02:10,480
So that's good.

23
00:02:11,570 --> 00:02:12,880
Let's do square.

24
00:02:14,740 --> 00:02:15,750
We got four.

25
00:02:15,760 --> 00:02:16,750
So that's good.

26
00:02:16,750 --> 00:02:19,440
So we can assume Pentagon will be fine.

27
00:02:19,450 --> 00:02:23,920
So now let's check the Octagon just to verify that we get eight.

28
00:02:24,970 --> 00:02:26,320
And now we have eight.

29
00:02:26,530 --> 00:02:29,700
So that is my solution to the assignment.

30
00:02:29,710 --> 00:02:34,180
