1
00:00:00,880 --> 00:00:06,910
OK, so before you write your first Java code, you will need two tools to be installed on your computer.

2
00:00:07,390 --> 00:00:13,640
The first one is a Java development kit, or JDK, which is actually an all you need development kit.

3
00:00:14,260 --> 00:00:21,070
It has a lot of components, but basically it's a software that can convert or with other words, compile

4
00:00:21,070 --> 00:00:29,740
your code that can be read by you, me or anybody else into a format that can be understood by computers.

5
00:00:30,250 --> 00:00:33,100
Then it can also execute Java applications.

6
00:00:33,670 --> 00:00:40,030
It can also grab the whole project into one Runnable file that can be double clicked and can be run

7
00:00:40,030 --> 00:00:41,710
on any operating systems.

8
00:00:42,400 --> 00:00:48,790
In addition, it can generate an HDMI file out of your Java documentation, which might be not commonly

9
00:00:48,790 --> 00:00:51,250
used, but it is also part of the case.

10
00:00:52,150 --> 00:00:58,870
And the scores we are going to use, Amazon's JDK, Amazon, Croteau, actually there are many JDK versions.

11
00:00:59,140 --> 00:01:05,150
Oracle provides two versions, a paid version and a free open source version.

12
00:01:05,590 --> 00:01:08,580
The difference between the two versions is quite small.

13
00:01:09,070 --> 00:01:10,720
They are almost identical.

14
00:01:10,720 --> 00:01:17,420
Functionally, the paid version provides better performance and it also has high end features.

15
00:01:17,920 --> 00:01:23,800
It is actually created for companies, but for learning, the free version is completely fine.

16
00:01:24,670 --> 00:01:32,630
Another popular JDK version is Adopt Open JDK, and probably the most popular is Amazon Karata.

17
00:01:33,220 --> 00:01:38,440
There are other performance updated JDK versions from Azor and RedHat.

18
00:01:38,980 --> 00:01:43,370
They provide improvement in speed, but they are both paid versions.

19
00:01:44,140 --> 00:01:46,690
OK, so why I choose Amazon creator.

20
00:01:47,170 --> 00:01:54,220
The first reason is that it is used on Amazon servers, so it is tested and widely used in production

21
00:01:54,220 --> 00:01:54,970
environment.

22
00:01:55,430 --> 00:02:02,390
Also, many big companies use Amazon services and using their servers to run Java applications.

23
00:02:02,890 --> 00:02:07,930
The second one is that James Gosling, the founder of Java, is working at Amazon.

24
00:02:08,210 --> 00:02:11,520
I think it is a quiet, huge plus for Amazon version.

25
00:02:12,280 --> 00:02:19,000
Also, Amazon provides long term support for both versions available on their website, so they will

26
00:02:19,000 --> 00:02:20,920
be there for a very long time.

27
00:02:21,310 --> 00:02:26,070
On top of the previous one, there are frequent updates for these versions.

28
00:02:26,320 --> 00:02:31,320
So if a major security issue found, there will be definitely an update.

29
00:02:31,900 --> 00:02:36,930
And lastly, it can be used interchangeably with other open JDK versions.

30
00:02:37,330 --> 00:02:43,420
So if you have two computers with different versions of open JDK, it doesn't matter.

31
00:02:43,690 --> 00:02:48,640
The code will run the same way on both machines because of these reasons.

32
00:02:48,670 --> 00:02:53,940
I think Amazon Kirito is the best choice for both students and companies.

33
00:02:54,640 --> 00:02:55,150
All right.

34
00:02:55,150 --> 00:02:58,430
So what's the other thing you need to be installed on your computer?

35
00:02:58,810 --> 00:03:05,110
It's an integrated development environment, or ID, which is actually an intelligent text editor for

36
00:03:05,110 --> 00:03:09,450
programming, and it has a lot of features to make coding much easier.

37
00:03:09,850 --> 00:03:14,420
For example, it highlights language keywords so you can read your code much easier.

38
00:03:14,920 --> 00:03:18,780
Also, it provides hints on how you can complete your code.

39
00:03:19,060 --> 00:03:26,560
For example, you start typing in something and the idea shows you the possible solutions and in addition,

40
00:03:26,590 --> 00:03:29,720
it detects errors and also underlines them.

41
00:03:30,320 --> 00:03:35,830
Moreover, you can connect it to version control systems like GitHub or so sorcery.

42
00:03:36,640 --> 00:03:41,440
On top of that, it analyzes your code and find duplications.

43
00:03:42,080 --> 00:03:45,700
There are other features as well, but these are the most important ones.

44
00:03:46,300 --> 00:03:52,180
In this course, we are going to use the most popular idea for Java development, intelligent ideas,

45
00:03:52,180 --> 00:03:53,080
free version.

46
00:03:53,200 --> 00:03:59,470
It is used by many big tech companies and also just brains created ideas for many other programming

47
00:03:59,470 --> 00:04:04,720
languages to the features of the free version will be definitely enough for discourse.

48
00:04:05,110 --> 00:04:11,230
In the next videos, I will show you how you can install JDK and intelligence for different operating

49
00:04:11,230 --> 00:04:11,890
systems.

50
00:04:12,460 --> 00:04:15,590
Choose videos based on your current operating system.

51
00:04:16,060 --> 00:04:16,920
See you there.
