1

00:00:00,840  -->  00:00:03,720
You can always go ahead and continue extending our project.

2

00:00:04,050  -->  00:00:07,070
So earlier we made changes in the data store class.

3

00:00:07,270  -->  00:00:07,620
OK.

4

00:00:07,620  -->  00:00:08,790
So we changed everything.

5

00:00:08,810  -->  00:00:11,700
Today all sectors from the collections framework chapter.

6

00:00:11,910  -->  00:00:16,630
So now let's go ahead and continue making changes in the other classes.

7

00:00:17,150  -->  00:00:18,450
So lunch not Djala.

8

00:00:18,450  -->  00:00:19,920
Here it is.

9

00:00:19,920  -->  00:00:21,650
So we have loaded that down.

10

00:00:22,200  -->  00:00:26,870
And the next thing that we are doing here is in the stock method.

11

00:00:27,240  -->  00:00:34,480
Here it is understocked meant there is going to be for each user it's going to similar browsing OK the

12

00:00:34,770  -->  00:00:36,250
bookmarking process.

13

00:00:36,270  -->  00:00:37,510
So that's what it is going to do.

14

00:00:37,530  -->  00:00:42,930
And Peukert response to the browser and we have this method called us but also we are passing a single

15

00:00:42,930  -->  00:00:46,320
user on the set of all bookmarks.

16

00:00:46,320  -->  00:00:54,030
Now here is after loading the dot we are fetching the users and also the bookmarks.

17

00:00:54,310  -->  00:00:57,900
OK but here are the users still using this.

18

00:00:57,900  -->  00:01:00,260
The idea is so we need to change that.

19

00:01:00,450  -->  00:01:07,080
So let's make it less of user and make this

20

00:01:13,380  -->  00:01:17,110
list awfullest off bookmark.

21

00:01:18,930  -->  00:01:23,000
And this data is being fetched using the manager's.

22

00:01:23,190  -->  00:01:23,600
OK.

23

00:01:23,670  -->  00:01:25,280
So we are using the manager's files.

24

00:01:25,290  -->  00:01:28,320
So let's go there.

25

00:01:28,440  -->  00:01:32,030
Here it is on managers is in walking the dog layer.

26

00:01:32,040  -->  00:01:36,330
Here it is andar is actually in the database.

27

00:01:36,420  -->  00:01:40,570
Normally the database calls are made from the Doblin.

28

00:01:40,590  -->  00:01:50,010
So let's dig this line in the user dhal and exchange this to this user is being invoked from use on

29

00:01:50,010  -->  00:01:55,470
manager Nerdist simply returning the data that it gets from Dow.

30

00:01:55,470  -->  00:01:57,140
So change that.

31

00:01:57,140  -->  00:01:59,100
And if you're going to launch not Java.

32

00:01:59,160  -->  00:02:00,990
So this has also changed.

33

00:02:01,110  -->  00:02:03,840
So no more compassionate and this line.

34

00:02:04,170  -->  00:02:05,410
Now let's do the same thing.

35

00:02:05,430  -->  00:02:13,680
Heard this and here it as bookmarks manager which is in marking bookmarks dhal which is in Woking to

36

00:02:13,680  -->  00:02:16,300
get bookmarks method here.

37

00:02:16,350  -->  00:02:22,430
So let's just dig this new the same thing again.

38

00:02:23,590  -->  00:02:29,420
We did a story this one in the bookmark manager.

39

00:02:29,460  -->  00:02:36,270
Also we do the same thing and and launch Also we do the same thing on the compilation and it has gone

40

00:02:36,310  -->  00:02:37,260
.

41

00:02:37,280  -->  00:02:43,760
Now these are some Brentham that that's it's not really about that for now actually we can change that

42

00:02:43,770  -->  00:02:50,510
also does make it less or more.

43

00:02:50,610  -->  00:02:58,000
We are done with that and the browse method in view is expecting this.

44

00:02:58,050  -->  00:03:07,590
So we can change this to the launch is clear of all completion errors.

45

00:03:07,590  -->  00:03:14,850
Now here we are in the view and we are getting the bookmarks and we are iterating through each of the

46

00:03:14,850  -->  00:03:15,880
bookmarks here.

47

00:03:15,960  -->  00:03:20,990
So that's the first thing here we are simulating a user who is going to bookmark.

48

00:03:21,300  -->  00:03:21,560
OK.

49

00:03:21,570  -->  00:03:24,240
Bookmarks all of them all of the bookmarks.

50

00:03:24,240  -->  00:03:25,670
He's going to bookmark some of them.

51

00:03:25,680  -->  00:03:27,420
So we are simulating that.

52

00:03:27,420  -->  00:03:30,310
So we just need to change this.

53

00:03:30,330  -->  00:03:30,640
OK.

54

00:03:30,660  -->  00:03:34,410
So in the foster tradition or it's going to be web links in the second movies under the hood you're

55

00:03:34,410  -->  00:03:39,360
just going to be books and he's looking at each of the bookmarks here.

56

00:03:39,360  -->  00:03:39,780
OK.

57

00:03:39,900  -->  00:03:43,820
So the users are directing is looking at each of the bookmarks here.

58

00:03:44,250  -->  00:03:44,520
OK.

59

00:03:44,520  -->  00:03:50,460
So this one would be bookmarklet this for loop and this second for loop as for individual bookmarks

60

00:03:50,760  -->  00:03:53,640
within that particular type of bookmark.

61

00:03:54,150  -->  00:03:56,050
So in the first iteration it would be ramblings.

62

00:03:56,070  -->  00:03:59,340
And the second it would be movies and in the third box.

63

00:03:59,370  -->  00:04:06,900
Now here we are in the in the previous version we are restricting the user to on the bookmark a certain

64

00:04:07,350  -->  00:04:08,870
number of bookmarks.

65

00:04:08,970  -->  00:04:09,490
OK.

66

00:04:09,630  -->  00:04:11,690
Beyond that he cannot bookmark.

67

00:04:11,700  -->  00:04:19,350
So that's some inflexibility I think we can remove got now bookmark bookmark the user can bookmark any

68

00:04:19,350  -->  00:04:20,570
number of bookmarks.

69

00:04:20,740  -->  00:04:24,190
OK Max limit would be bookmarks Dawk.

70

00:04:24,480  -->  00:04:27,490
I mean the maximum number of bookmarks is that the system has.

71

00:04:27,900  -->  00:04:29,260
So that is done.

72

00:04:29,280  -->  00:04:35,840
So seems like this is also done on we know that the bookmarking decision is made we are randomisation

73

00:04:36,810  -->  00:04:44,290
But if we are going to implement the iPod later we will get the decision from the user interface itself

74

00:04:44,290  -->  00:04:44,420
.

75

00:04:44,450  -->  00:04:45,150
OK.

76

00:04:45,540  -->  00:04:52,950
And the same thing is also happening after bookmarking if the user happens to be an editor or the chief

77

00:04:52,950  -->  00:04:53,480
editor.

78

00:04:53,520  -->  00:04:57,540
The user can actually set the bookmark as kid friendly.

79

00:04:57,750  -->  00:05:02,880
OK so this is a code for that if in case you have forgotten you can just go back.

80

00:05:03,090  -->  00:05:06,740
You can view that court on Similarly the book here.

81

00:05:06,750  -->  00:05:12,300
This court will well will see if the book if the particular bookmark can be shared or.

82

00:05:12,330  -->  00:05:14,540
The third party site or not.

83

00:05:14,870  -->  00:05:20,440
And all of the decisions here get shared decision and get good the state as a decision.

84

00:05:20,490  -->  00:05:23,750
So all the decisions are done via randomisation.

85

00:05:24,030  -->  00:05:31,170
Hopefully we will change that also to take the input from the user from the UI or see what we now hear

86

00:05:31,190  -->  00:05:31,540
.

87

00:05:31,860  -->  00:05:41,600
OK so once the user in the view here once the user is bookmarking an item we are invoking the same user

88

00:05:41,610  -->  00:05:42,120
bookmark.

89

00:05:42,150  -->  00:05:43,810
So lets go there.

90

00:05:43,870  -->  00:05:52,560
Ancel user bookmark is this method is in the book month manager and a Saudi It is an bookmark controller

91

00:05:53,160  -->  00:05:54,030
on the control tower.

92

00:05:54,040  -->  00:05:57,550
So from the UI from the view part we are invoking the controller.

93

00:05:57,570  -->  00:05:58,750
Thats the normal process.

94

00:05:58,780  -->  00:06:05,340
Any any web application in and which follows and MVC framework model from the controller we are invoking

95

00:06:05,340  -->  00:06:10,580
the same method a set of user book Walk and bookmark manager in the Manager class.

96

00:06:10,620  -->  00:06:16,890
So here we are creating this instance called user bookmark which is passed to user and bookmark.

97

00:06:17,040  -->  00:06:22,710
So you may recall that we are creating this user bookmark instance and we are saying that it is being

98

00:06:23,280  -->  00:06:25,440
bookmarked by this particular user.

99

00:06:25,860  -->  00:06:26,510
OK.

100

00:06:26,630  -->  00:06:33,570
Its in the user user is the input on that particular user as bookmarking this particular book back.

101

00:06:33,750  -->  00:06:40,650
OK so which user is bookmarking which bookmark as something that is stored in this in this instance

102

00:06:41,460  -->  00:06:46,590
Hanaford is an instance off of eyeblink than we are doing something we are actually downloading the

103

00:06:46,590  -->  00:06:48,660
link and we are writing it here.

104

00:06:48,930  -->  00:06:49,560
So.

105

00:06:49,590  -->  00:06:55,430
So thats all information so we have and we have implemented quite a bit so far.

106

00:06:55,830  -->  00:07:02,340
And here we are in walking does save user a bookmark because we want to save this information to the

107

00:07:02,340  -->  00:07:04,710
database so we are working there.

108

00:07:04,740  -->  00:07:09,480
So lets go here on this doll as being past the user bookmark.

109

00:07:09,530  -->  00:07:16,770
And it is been walking the odd method in the store so lets more there and here it is on this odd method

110

00:07:16,780  -->  00:07:17,150
.

111

00:07:17,520  -->  00:07:20,380
Ideally it would insert the date time to the database.

112

00:07:20,490  -->  00:07:26,070
But since we are managing everything in the date just across are distorting the use bookmark information

113

00:07:26,160  -->  00:07:28,570
in this user bookmarks ID.

114

00:07:28,870  -->  00:07:29,190
OK.

115

00:07:29,220  -->  00:07:34,400
So we are going to change that also because we want only data structures from collections frameworks

116

00:07:34,410  -->  00:07:45,500
so lets go here use our bookmarks and its changed list of user bookmark

117

00:07:52,010  -->  00:07:56,140
.

118

00:07:57,690  -->  00:07:58,620
So that's changed

119

00:07:59,140  -->  00:08:06,320
.

120

00:08:07,980  -->  00:08:10,080
And we are starting it with that.

121

00:08:10,460  -->  00:08:17,160
And we don't need this also anymore.

122

00:08:21,380  -->  00:08:25,200
It's here you can just remove that.

123

00:08:25,410  -->  00:08:27,150
Keeping track of the index.

124

00:08:27,540  -->  00:08:29,300
So thats about it.

125

00:08:29,760  -->  00:08:38,070
So let me just your on this here at On-Star Java keynoting data and user are browsing items

126

00:08:40,920  -->  00:08:45,540
user 3 user 4 and so on and we are done.

127

00:08:45,660  -->  00:08:46,530
So you're done with that.

128

00:08:46,560  -->  00:08:50,410
So we have change the program we have extended it now.

129

00:08:50,580  -->  00:08:57,630
All ideas are removed and we have replaced them vet who had done with the collections framework data

130

00:08:57,630  -->  00:08:58,380
structures.

131

00:08:58,390  -->  00:08:58,610
Okay.

132

00:08:58,620  -->  00:09:06,160
And we got the benefit off of not having to use fixed size data structures.

133

00:09:06,230  -->  00:09:06,480
Okay.

134

00:09:06,490  -->  00:09:11,400
During recreation time we had to set the fixed the size of Doddie that's no longer needed.

135

00:09:11,790  -->  00:09:15,020
And that did us actors are also automatically extendable.

136

00:09:15,030  -->  00:09:17,420
So it's a small change but a nice change.

137

00:09:17,490  -->  00:09:17,790
Okay.

138

00:09:17,790  -->  00:09:25,670
So we could clearly see the benefit that we how of using data us in the collections framework.

139

00:09:25,680  -->  00:09:27,380
Although our aim is very useful.

140

00:09:27,570  -->  00:09:32,340
But in this case we could see the flexibility that we could get from collection's free market sectors

141

00:09:32,410  -->  00:09:32,830
.

142

00:09:33,240  -->  00:09:33,500
Okay.

143

00:09:33,510  -->  00:09:34,320
So that's about it.

144

00:09:34,320  -->  00:09:39,520
So please go ahead and make this the changes that we have done in this in the previous Nisson.

145

00:09:39,540  -->  00:09:44,760
I know with that I think we have also given as much of the project and we will see how we can extend

146

00:09:44,760  -->  00:09:46,620
it further later.

147

00:09:46,650  -->  00:09:48,900
So thank you and happy coding
