02 - Core Java/005 First code Setup_en.srt

1
00:00:00,000 --> 00:00:03,000
(gentle music)

2
00:00:03,000 --> 00:00:05,000
-: Okay, now let's write our first code.

3
00:00:05,000 --> 00:00:07,000
Hello World in IntelliJ IDEA.

4
00:00:07,000 --> 00:00:08,000
and try the community version.

5
00:00:08,000 --> 00:00:12,000
So I'm going to close the Ultimate version.

6
00:00:12,000 --> 00:00:14,000
It's already closed and now how do we do it?

7
00:00:14,000 --> 00:00:15,000
So very simple.

8
00:00:15,000 --> 00:00:17,000
We open the IntelliJ Idea Community version.

9
00:00:17,000 --> 00:00:18,000
You will see this prompt and by default,

10
00:00:18,000 --> 00:00:21,000
if it is new for you you will not see any of the project

11
00:00:21,000 --> 00:00:22,000
which you can see here.

12
00:00:22,000 --> 00:00:26,000
And now if I click on new project, so basically

13
00:00:26,000 --> 00:00:28,000
whenever you build projects or whenever you write any code,

14
00:00:28,000 --> 00:00:30,000
so there was a days where you used to create

15
00:00:30,000 --> 00:00:33,000
a normal notepad file or a TXT file

16
00:00:33,000 --> 00:00:35,000
where you write your Java code

17
00:00:35,000 --> 00:00:38,000
and then you compile that with the help of the command line.

18
00:00:38,000 --> 00:00:40,000
So we have to create our project,

19
00:00:40,000 --> 00:00:41,000
okay, so what is a project?

20
00:00:41,000 --> 00:00:43,000
A folder where you have different project structure,

21
00:00:43,000 --> 00:00:45,000
different configuration files and all this stuff.

22
00:00:45,000 --> 00:00:46,000
Now since we are writing the first code,

23
00:00:46,000 --> 00:00:48,000
let's not look at the project structure.

24
00:00:48,000 --> 00:00:49,000
So click on the new project.

25
00:00:49,000 --> 00:00:52,000
It will ask you for certain things.

26
00:00:52,000 --> 00:00:53,000
So this, this is the prompt you will get.

27
00:00:53,000 --> 00:00:55,000
Make sure that you are on this new project tab.

28
00:00:55,000 --> 00:00:57,000
And here you can name any project.

29
00:00:57,000 --> 00:00:59,000
So I will say DemoFirst

30
00:01:01,000 --> 00:01:04,000
and you can save this somewhere in your location.

31
00:01:04,000 --> 00:01:07,000
I will just keep this on desktop, path selected.

32
00:01:07,000 --> 00:01:09,000
And now you can choose a language for this project.

33
00:01:09,000 --> 00:01:11,000
So we are running Java, so you can stick to Java,

34
00:01:11,000 --> 00:01:13,000
build system by default, select IntelliJ

35
00:01:13,000 --> 00:01:16,000
will understand what is Maven later.

36
00:01:16,000 --> 00:01:18,000
And then you select your JDK version.

37
00:01:18,000 --> 00:01:20,000
Now depend upon which one you have downloaded.

38
00:01:20,000 --> 00:01:23,000
So if you have 17, 21 you can choose any of it.

39
00:01:23,000 --> 00:01:26,000
I'm going for 21 here and click on Create.

40
00:01:26,000 --> 00:01:29,000
It will create a project for you, a very simple project

41
00:01:29,000 --> 00:01:32,000
and by default you will have this one code.

42
00:01:32,000 --> 00:01:33,000
And by default it will show you hello world.

43
00:01:33,000 --> 00:01:35,000
We just want to see if this works.

44
00:01:35,000 --> 00:01:37,000
So I will just simply say save.

45
00:01:37,000 --> 00:01:41,000
There are some issues in the code, which I can see here,

46
00:01:41,000 --> 00:01:42,000
or simply click on Run.

47
00:01:42,000 --> 00:01:43,000
Okay, no problem.

48
00:01:43,000 --> 00:01:45,000
I don't know what the issue is.

49
00:01:45,000 --> 00:01:46,000
Might be some issue with the ID.

50
00:01:46,000 --> 00:01:49,000
And you can see we we got the output as hello world.

51
00:01:49,000 --> 00:01:51,000
Now at this point, don't stress much on this things.

52
00:01:51,000 --> 00:01:53,000
It is simple, hello world code.

53
00:01:53,000 --> 00:01:56,000
Now in the upcoming videos, whenever you see any topic,

54
00:01:56,000 --> 00:01:59,000
it is by default we are using VS Code there

55
00:01:59,000 --> 00:02:00,000
for the code Java.

56
00:02:00,000 --> 00:02:02,000
And if you want to try and IntelliJ Idea,

57
00:02:02,000 --> 00:02:05,000
just continue with this ID and type the same code.

58
00:02:05,000 --> 00:02:07,000
You will have everything here and with the same output,

59
00:02:07,000 --> 00:02:10,000
of course the output will not change based on the IDs.

60
00:02:10,000 --> 00:02:12,000
So yeah, that's about how do we write our first code

61
00:02:12,000 --> 00:02:13,000
in the IntelliJ.

62
00:02:13,000 --> 00:02:15,000
So you have an option, you can continue with VS Code

63
00:02:15,000 --> 00:02:18,000
or IntelliJ or any of your favorite ID.

64
00:02:18,000 --> 00:02:19,000
Bye.
