| (gentle music) |
|
|
| 2 |
| 00:00:03,000 |
| -: Okay, now let's write our first code. |
|
|
| 3 |
| 00:00:05,000 |
| Hello World in IntelliJ IDEA. |
|
|
| 4 |
| 00:00:07,000 |
| and try the community version. |
|
|
| 5 |
| 00:00:08,000 |
| So I'm going to close the Ultimate version. |
|
|
| 6 |
| 00:00:12,000 |
| It's already closed and now how do we do it? |
|
|
| 7 |
| 00:00:14,000 |
| So very simple. |
|
|
| 8 |
| 00:00:15,000 |
| We open the IntelliJ Idea Community version. |
|
|
| 9 |
| 00:00:17,000 |
| You will see this prompt and by default, |
|
|
| 10 |
| 00:00:18,000 |
| if it is new for you you will not see any of the project |
|
|
| 11 |
| 00:00:21,000 |
| which you can see here. |
|
|
| 12 |
| 00:00:22,000 |
| And now if I click on new project, so basically |
|
|
| 13 |
| 00:00:26,000 |
| whenever you build projects or whenever you write any code, |
|
|
| 14 |
| 00:00:28,000 |
| so there was a days where you used to create |
|
|
| 15 |
| 00:00:30,000 |
| a normal notepad file or a TXT file |
|
|
| 16 |
| 00:00:33,000 |
| where you write your Java code |
|
|
| 17 |
| 00:00:35,000 |
| and then you compile that with the help of the command line. |
|
|
| 18 |
| 00:00:38,000 |
| So we have to create our project, |
|
|
| 19 |
| 00:00:40,000 |
| okay, so what is a project? |
|
|
| 20 |
| 00:00:41,000 |
| A folder where you have different project structure, |
|
|
| 21 |
| 00:00:43,000 |
| different configuration files and all this stuff. |
|
|
| 22 |
| 00:00:45,000 |
| Now since we are writing the first code, |
|
|
| 23 |
| 00:00:46,000 |
| let's not look at the project structure. |
|
|
| 24 |
| 00:00:48,000 |
| So click on the new project. |
|
|
| 25 |
| 00:00:49,000 |
| It will ask you for certain things. |
|
|
| 26 |
| 00:00:52,000 |
| So this, this is the prompt you will get. |
|
|
| 27 |
| 00:00:53,000 |
| Make sure that you are on this new project tab. |
|
|
| 28 |
| 00:00:55,000 |
| And here you can name any project. |
|
|
| 29 |
| 00:00:57,000 |
| So I will say DemoFirst |
|
|
| 30 |
| 00:01:01,000 |
| and you can save this somewhere in your location. |
|
|
| 31 |
| 00:01:04,000 |
| I will just keep this on desktop, path selected. |
|
|
| 32 |
| 00:01:07,000 |
| And now you can choose a language for this project. |
|
|
| 33 |
| 00:01:09,000 |
| So we are running Java, so you can stick to Java, |
|
|
| 34 |
| 00:01:11,000 |
| build system by default, select IntelliJ |
|
|
| 35 |
| 00:01:13,000 |
| will understand what is Maven later. |
|
|
| 36 |
| 00:01:16,000 |
| And then you select your JDK version. |
|
|
| 37 |
| 00:01:18,000 |
| Now depend upon which one you have downloaded. |
|
|
| 38 |
| 00:01:20,000 |
| So if you have 17, 21 you can choose any of it. |
|
|
| 39 |
| 00:01:23,000 |
| I'm going for 21 here and click on Create. |
|
|
| 40 |
| 00:01:26,000 |
| It will create a project for you, a very simple project |
|
|
| 41 |
| 00:01:29,000 |
| and by default you will have this one code. |
|
|
| 42 |
| 00:01:32,000 |
| And by default it will show you hello world. |
|
|
| 43 |
| 00:01:33,000 |
| We just want to see if this works. |
|
|
| 44 |
| 00:01:35,000 |
| So I will just simply say save. |
|
|
| 45 |
| 00:01:37,000 |
| There are some issues in the code, which I can see here, |
|
|
| 46 |
| 00:01:41,000 |
| or simply click on Run. |
|
|
| 47 |
| 00:01:42,000 |
| Okay, no problem. |
|
|
| 48 |
| 00:01:43,000 |
| I don't know what the issue is. |
|
|
| 49 |
| 00:01:45,000 |
| Might be some issue with the ID. |
|
|
| 50 |
| 00:01:46,000 |
| And you can see we we got the output as hello world. |
|
|
| 51 |
| 00:01:49,000 |
| Now at this point, don't stress much on this things. |
|
|
| 52 |
| 00:01:51,000 |
| It is simple, hello world code. |
|
|
| 53 |
| 00:01:53,000 |
| Now in the upcoming videos, whenever you see any topic, |
|
|
| 54 |
| 00:01:56,000 |
| it is by default we are using VS Code there |
|
|
| 55 |
| 00:01:59,000 |
| for the code Java. |
|
|
| 56 |
| 00:02:00,000 |
| And if you want to try and IntelliJ Idea, |
|
|
| 57 |
| 00:02:02,000 |
| just continue with this ID and type the same code. |
|
|
| 58 |
| 00:02:05,000 |
| You will have everything here and with the same output, |
|
|
| 59 |
| 00:02:07,000 |
| of course the output will not change based on the IDs. |
|
|
| 60 |
| 00:02:10,000 |
| So yeah, that's about how do we write our first code |
|
|
| 61 |
| 00:02:12,000 |
| in the IntelliJ. |
|
|
| 62 |
| 00:02:13,000 |
| So you have an option, you can continue with VS Code |
|
|
| 63 |
| 00:02:15,000 |
| or IntelliJ or any of your favorite ID. |
|
|
| 64 |
| 00:02:18,000 |
| Bye. |
