1

00:00:01,070  -->  00:00:07,370
Now let's look at strings of string manipulation is one of the most common activities in programming

2

00:00:07,370  -->  00:00:08,260
.

3

00:00:08,270  -->  00:00:14,690
That's because strings represent text and we know that it is impossible to imagine any application VIDOT

4

00:00:14,750  -->  00:00:20,090
next strings in are unique due to the way they get stored internally.

5

00:00:20,340  -->  00:00:25,320
If you don't have a clear understanding of strings in Java then you may end up writing very inefficient

6

00:00:25,320  -->  00:00:26,010
code.

7

00:00:26,330  -->  00:00:31,010
So to try to cover everything related to strings so that we can use it in the right way.

8

00:00:32,590  -->  00:00:39,400
A string is simply an object of the class jobs are not blank docstring the fact that stringless is part

9

00:00:39,400  -->  00:00:43,550
of our Rockline package tells us that it is a fundamental class job.

10

00:00:45,160  -->  00:00:49,540
So we can simply instantiate the String class to create String objects.

11

00:00:49,540  -->  00:00:57,110
In this case a variable S represents an empty string not if you want a variable as to represent some

12

00:00:57,170  -->  00:01:01,050
text like hello then we can invoke a different constructor.

13

00:01:01,460  -->  00:01:05,930
In this example the argument passed to the constructor is a Citrin return.

14

00:01:06,200  -->  00:01:12,580
So a string literal consists of zero or more characters enclosed in double quotes Well Carter letters

15

00:01:12,580  -->  00:01:14,200
are enclosed in single quotes.

16

00:01:14,200  -->  00:01:20,330
String literals are enclosed in double quotes know this particular constructor has a single parameter

17

00:01:20,630  -->  00:01:28,220
that is an object reference of byte string so it means that you DOCSIS String objects it also means

18

00:01:28,220  -->  00:01:31,940
that a string literal is also a String object.

19

00:01:32,540  -->  00:01:39,720
So intimately as ringleader is Bastos a string object or insert a string we can you can also pass an

20

00:01:39,810  -->  00:01:46,420
object reference of by a string that is all we are creating an object reference of pipe string.

21

00:01:46,420  -->  00:01:54,040
We are creating it by passing another object reference as input to the constructor Alternatively you

22

00:01:54,050  -->  00:01:59,760
can also do this very first create a character tree representing the text Hello.

23

00:02:00,010  -->  00:02:07,160
Then the characters race past us and put to run off the constructor's finally we can also create strengths

24

00:02:07,460  -->  00:02:14,690
just like the way we create perimeter variables simply assign a string literal with a variable as not

25

00:02:14,690  -->  00:02:18,160
that he had available as is still an object reference.

26

00:02:18,470  -->  00:02:22,680
So don't think that it's a primitive variable just because we are sending a letter.

27

00:02:23,120  -->  00:02:26,410
You can also see that the variable type is a class or not.

28

00:02:26,420  -->  00:02:33,180
But it go get a Also this is the recommended way to create strings are strings created using string

29

00:02:33,180  -->  00:02:38,410
literals are internally implemented in an efficient way as we will soon see.

30

00:02:38,730  -->  00:02:43,770
So all the previous approaches of creating strings using the new keyword are not recommended.

31

00:02:46,120  -->  00:02:54,360
Not that in Donelly string class use a psychotic rate to that text but we know that in characters I

32

00:02:54,360  -->  00:03:00,210
didn't and the data presented using you'd be 16 and coding scheme which is an implementation of Unicode

33

00:03:00,220  -->  00:03:08,400
characters that what this means is that a string in Java is basically a sequence off Unicode characters

34

00:03:09,320  -->  00:03:15,290
here we are using the term sequence as strings and Dunalley using characters to store that text.

35

00:03:17,210  -->  00:03:19,640
Estrin in July is also immutable.

36

00:03:20,090  -->  00:03:24,860
That is once a string of dip is created its value can never be changed.

37

00:03:25,100  -->  00:03:33,050
String mutability will be discussed later so always keep in mind that a string object basically contains

38

00:03:33,050  -->  00:03:36,670
an immutable sequence of Unicode characters.

39

00:03:38,480  -->  00:03:42,070
String is given special treatment in Java it's common usage.

40

00:03:42,440  -->  00:03:48,970
Let's look at some off its special features we have already seen that like primitives a string can be

41

00:03:48,970  -->  00:03:52,930
constructed by directly assigning a string literal.

42

00:03:52,930  -->  00:04:00,100
You can do this for regular job objects but one exception is baulks primitives or wrapper classes which

43

00:04:00,100  -->  00:04:03,270
we briefly discussed while covering switch statements.

44

00:04:03,270  -->  00:04:06,180
They can be directly assigned litotes also.

45

00:04:06,310  -->  00:04:13,170
For example an object reference of type integer can be directly assigned an int..

46

00:04:13,270  -->  00:04:15,290
We'll be looking at baulks primitives later.

47

00:04:17,010  -->  00:04:22,740
If you recall we mentioned that bless our pricker which is one of the Artomatic operators can also be

48

00:04:22,740  -->  00:04:29,490
additionally used for string concatenation that is as you can see here we can use bless to concatenate

49

00:04:29,620  -->  00:04:30,160
strings.

50

00:04:30,230  -->  00:04:31,520
Hello and goodbye.

51

00:04:31,970  -->  00:04:39,260
So bailable as we be the little hello world literally a lot to discuss about string concatenation as

52

00:04:39,260  -->  00:04:47,440
there is a performance implication associated with it finally all strings created using string literals

53

00:04:47,680  -->  00:04:53,900
are stored in a special area of memory called string this does not happen with strings that are created

54

00:04:53,900  -->  00:04:55,470
using nucula.

55

00:04:55,880  -->  00:05:02,050
That is they don't get stored in that string when the main benefit that drink will provide is that if

56

00:05:02,290  -->  00:05:08,080
strings are created using the same string return then they both would be represented by the same string

57

00:05:08,080  -->  00:05:09,700
object in the string.

58

00:05:10,150  -->  00:05:12,320
So basically memory is served here.

59

00:05:12,910  -->  00:05:18,700
But if you create two strings with a Nuki word and they both have the same text then they are still

60

00:05:18,710  -->  00:05:21,820
represented by different string objects.

61

00:05:21,820  -->  00:05:27,030
This was the reason why it was recommended to create strings by assigning literals are not true.

62

00:05:27,040  -->  00:05:35,120
Using the new keyword and you have even discussed Trinkle later in detail in a lesson so that's about

63

00:05:35,120  -->  00:05:35,840
it.

64

00:05:35,840  -->  00:05:41,020
We now understand what a string is and how it can be created in the next few lessons.

65

00:05:41,030  -->  00:05:43,520
We will try to explore everything about strings
