1 00:00:00,350 --> 00:00:05,880 Hire everyone in the state or you're going to go ahead and actually create our first job application. 2 00:00:06,060 --> 00:00:09,530 So first we need to open the eclipse ideally. 3 00:00:09,630 --> 00:00:12,540 So as you can see here it's kind of opened the idea for us. 4 00:00:12,540 --> 00:00:16,790 And by the way ID stands for Integrated Development Kit. 5 00:00:16,920 --> 00:00:23,640 So actually for the first and you're opening the eclipse in your system it's going to ask you a question 6 00:00:23,640 --> 00:00:30,870 that I really want to actually save your project so you can actually choose the path for saving of project 7 00:00:30,900 --> 00:00:32,380 and then click on OK. 8 00:00:32,760 --> 00:00:34,790 And then it's going to open the eclipse for you. 9 00:00:35,100 --> 00:00:41,610 So first let me show you how you actually can change the theme of your ID and the font size. 10 00:00:41,640 --> 00:00:47,310 So if you are using a match or machine you can actually go to Eclipse and click on preferences. 11 00:00:47,430 --> 00:00:53,520 But if you are using a Windows machine you can go to Windows and click on preferences at the bottom 12 00:00:53,520 --> 00:00:53,730 here. 13 00:00:53,730 --> 00:00:54,330 OK. 14 00:00:54,600 --> 00:00:56,080 So I don't have that option here. 15 00:00:56,460 --> 00:01:00,850 So because I have got a Mac I can go through eclipse references. 16 00:01:01,050 --> 00:01:04,110 So and then as you can see here General. 17 00:01:04,200 --> 00:01:07,240 And then you need to open the general rule by clicking on this arrow here. 18 00:01:07,590 --> 00:01:12,800 Appearance as you can see here we can get you to change the theme of our ID here. 19 00:01:13,130 --> 00:01:13,660 OK. 20 00:01:13,780 --> 00:01:19,030 We can change the color and form to film and we need to actually click on apply. 21 00:01:19,050 --> 00:01:19,690 OK. 22 00:01:20,190 --> 00:01:27,120 And for the actually font size we need to make sure to open the appearance appearance here click on 23 00:01:27,120 --> 00:01:35,310 colors and phones and then you need to actually open this basic folder here and click on text font and 24 00:01:35,310 --> 00:01:36,910 then click on it edits. 25 00:01:37,410 --> 00:01:44,190 And here you can actually change the font size and a font of your actually ID. 26 00:01:44,220 --> 00:01:44,870 OK. 27 00:01:45,240 --> 00:01:48,830 So that's it for changing the settings. 28 00:01:48,840 --> 00:01:49,100 OK. 29 00:01:49,110 --> 00:01:50,820 And then click on apply and click on OK. 30 00:01:50,940 --> 00:02:00,690 So for creating a project you can actually go to find new and Java project OK for the project name just 31 00:02:00,690 --> 00:02:08,960 type in Heibel and then don't change anything here just leave the other options as default and click 32 00:02:08,960 --> 00:02:10,140 on finish. 33 00:02:10,790 --> 00:02:14,970 And as you can see here it can actually create the hard to Heyworth project for us. 34 00:02:15,260 --> 00:02:21,850 So first let me tell you that this JRA system library here does and it does actually include the section 35 00:02:21,850 --> 00:02:30,590 include the files the jar files were actually helping us to create job applications so that we don't 36 00:02:30,590 --> 00:02:33,280 actually do anything about these files. 37 00:02:33,290 --> 00:02:35,550 Ok we don't want to change them. 38 00:02:35,750 --> 00:02:36,300 OK. 39 00:02:36,530 --> 00:02:39,260 So just click on this as RC As you can see here. 40 00:02:39,260 --> 00:02:43,730 This is the RC or source folder that we need to actually put our job files in it. 41 00:02:43,730 --> 00:02:44,280 OK. 42 00:02:44,660 --> 00:02:46,330 So we need a Java class. 43 00:02:46,400 --> 00:02:47,000 OK. 44 00:02:47,330 --> 00:02:50,410 So class is a template to actually create objects. 45 00:02:50,450 --> 00:02:56,660 OK so don't worry if that if this doesn't make sense to you these concepts of classes or objects later 46 00:02:56,660 --> 00:02:59,380 in this section you will be more familiar with these concepts. 47 00:02:59,390 --> 00:03:07,070 So first just memorize that we need a class to actually create our job application which a class is 48 00:03:07,070 --> 00:03:10,610 a very important concept in object oriented programming. 49 00:03:10,790 --> 00:03:18,680 So in order to create a class you need to actually create these hybrid or SIRC folder and right clicking 50 00:03:18,680 --> 00:03:24,590 on it new class or you can actually find a new class. 51 00:03:24,590 --> 00:03:25,310 OK. 52 00:03:25,760 --> 00:03:32,650 So for the class name I'll always be sure to actually start your class names with the uppercase loader. 53 00:03:32,840 --> 00:03:36,520 So I actually named my class name like hi world. 54 00:03:37,820 --> 00:03:47,810 And you can see here my world or you can call it mean OK and for the modifiers whose public you will 55 00:03:47,810 --> 00:03:51,680 be more familiar with this public package and this other stuff. 56 00:03:51,680 --> 00:03:58,130 So but for this project just use public and don't change anything here. 57 00:03:58,130 --> 00:03:59,220 Just click on finish. 58 00:03:59,240 --> 00:03:59,810 OK. 59 00:04:00,290 --> 00:04:07,160 So and then it's going to actually create the main Java class for us as you can see here and it has 60 00:04:07,160 --> 00:04:10,350 created a default package for us as you can see here. 61 00:04:10,610 --> 00:04:14,740 A package is just a way to actually organize our Java files. 62 00:04:14,890 --> 00:04:15,420 OK. 63 00:04:15,550 --> 00:04:20,050 It helps us to organize our job our project and job files. 64 00:04:20,240 --> 00:04:24,950 So our in the section I will be talking to more about this package. 65 00:04:25,180 --> 00:04:25,700 OK. 66 00:04:25,860 --> 00:04:28,190 What in this application is a java project. 67 00:04:28,190 --> 00:04:34,860 I just want to show you how you can output subtexts in the current concert area at the bottom here. 68 00:04:35,120 --> 00:04:41,690 So if you don't have this concert area open you need to actually go to the window at the top should 69 00:04:41,720 --> 00:04:43,610 view and click on cancel. 70 00:04:43,670 --> 00:04:44,470 OK. 71 00:04:44,840 --> 00:04:52,950 So let me tell you that all Java programs need our starting point in order to run our codes. 72 00:04:52,970 --> 00:04:59,000 So what is this starting point this starting point is just the Meffert is just the main method. 73 00:04:59,090 --> 00:04:59,680 OK. 74 00:04:59,810 --> 00:05:02,380 So how we can create a main method. 75 00:05:02,540 --> 00:05:10,060 So this is the way we can create a meaningful public static void main. 76 00:05:10,490 --> 00:05:16,340 And then we need to open the apprentice's and inside the prefaces just actually type in a strange with 77 00:05:16,340 --> 00:05:22,060 a capital S and open and close the brackets and then type in arcs. 78 00:05:22,340 --> 00:05:27,840 OK arguments and US Open and close this method with the curly braces. 79 00:05:27,890 --> 00:05:32,990 So as you can see here this is the public modifier. 80 00:05:32,990 --> 00:05:34,630 Static void. 81 00:05:34,850 --> 00:05:38,870 These concepts may not actually make any sense to you right now. 82 00:05:38,990 --> 00:05:45,680 Don't for me for now just know that this is just a main actually the main method and this is a starting 83 00:05:45,680 --> 00:05:46,130 point. 84 00:05:46,130 --> 00:05:50,170 This is just a starting point for actually running our code. 85 00:05:50,350 --> 00:05:54,550 Ok but for now just know that this is the actually it is void. 86 00:05:54,780 --> 00:05:58,910 It means that this method doesn't return anything any value to us. 87 00:05:59,010 --> 00:06:02,220 It just actually execute some code. 88 00:06:02,420 --> 00:06:09,320 And this is the name of one method and you should know that Java is a case sensitive language so it 89 00:06:09,320 --> 00:06:16,020 is very important that you just type in your method name of the lowercase M. 90 00:06:16,040 --> 00:06:17,180 OK mate. 91 00:06:17,470 --> 00:06:24,110 And these are just arguments for RMF and this is the arguments and this is the type of argument which 92 00:06:24,410 --> 00:06:28,060 I will be talking more about this range strange brackets here. 93 00:06:28,070 --> 00:06:28,850 OK. 94 00:06:29,100 --> 00:06:34,600 Just for now let me show you how you can out with some text and the concert area. 95 00:06:34,850 --> 00:06:39,030 So now just type in System system OK. 96 00:06:39,470 --> 00:06:44,380 That's how dots print. 97 00:06:45,130 --> 00:06:51,370 And then open the parenthesis and inside the parenthesis just like in high water. 98 00:06:52,050 --> 00:06:56,750 And at the end of your statement and at the end of all your statements you need to put a semicolon. 99 00:06:56,760 --> 00:07:01,100 If you don't what is actually a semicolon it can actually complete. 100 00:07:01,110 --> 00:07:07,030 The English is going to complain and says syntax error in zero semicolon to complete blank statements. 101 00:07:07,070 --> 00:07:12,660 OK so we need to put that semicolon at the end of our actually statements. 102 00:07:12,930 --> 00:07:17,010 So you may ask that why don't we add a semicolon here or here. 103 00:07:17,370 --> 00:07:25,450 So let me point out that when you are declaring a method what a class is closing curly braces imply 104 00:07:25,690 --> 00:07:29,310 that you actually you have close your method or class. 105 00:07:29,310 --> 00:07:30,350 OK. 106 00:07:30,480 --> 00:07:33,230 This is like a semicolon at the end of our statements. 107 00:07:33,330 --> 00:07:39,580 So now when we want to actually run an application how we can run our application you need to actually 108 00:07:39,590 --> 00:07:44,470 just click on this highway world run as Java application. 109 00:07:44,660 --> 00:07:45,090 OK. 110 00:07:45,090 --> 00:07:50,340 Just click on this job application and then it's going to actually run an application and this is the 111 00:07:50,340 --> 00:07:51,900 Heibel text. 112 00:07:52,170 --> 00:07:52,680 OK. 113 00:07:52,860 --> 00:07:55,040 So congratulations. 114 00:07:55,050 --> 00:07:59,940 This is your first job application and you are now a Java programmer. 115 00:08:00,300 --> 00:08:03,970 So thanks for watching and I'll see you in the next tutorial.
