The Challenge

[MUSIC] 0:00 Hey hey, first off, 0:04 I wanna say awesome job choosing to make practice part of your routine. 0:05 Practice is an excellent way to make sure that what you've been learning 0:10 is sticking. 0:14 Now, this specific practice session is one of a series that we hope to create 0:15 over time, so please, make sure you let us know how you liked it and 0:19 if you'd like to see more of these. 0:23 For this session, I'd like you to practice doing IO. 0:24 Now remember, that stands for Input and Output. 0:28 Taking input from the user, and outputting it to the console. 0:30 As long as you've completed Stage 2 of the Java Basics Course, 0:34 you will have the proper skills to complete this practice. 0:38 Now, I've attached a new workspace to this video, and it looks like this. 0:41 Now, this is the basic shell of a Java application. 0:46 And I've gone ahead and I've imported the console object for you. 0:49 And it's all ready for you to use. 0:53 So in order to do this practice, the idea 0:55 is that you're going to read through these to-do's here and complete them. 0:57 Now the point of this little program is to be a greeter to 1:01 someone entering a place of your choosing, actually. 1:04 You know, like how some stores have people that greet you when you come in. 1:07 And in fact I have an example project, I'm not going to show you the code, 1:10 it's hidden underneath here. 1:14 So what's gonna happen, you'll notice that the file is called Greeter.java. 1:16 So we're gonna compile it, right? 1:19 We're gonna clear the screen, compile it, and then we're gonna run it. 1:20 So this is what it looks like when it runs. 1:23 Now, see I get those commands too. 1:25 A lot of people complain in the Java basics course that they don't see those, 1:27 but here it is. 1:30 I'm getting them too. 1:31 So my first name is Craig. 1:32 And it says, hello Craig! 1:35 Welcome to Kwik E Mart, cuz Kwik E Mart is what I chose. 1:36 Let's take a look at those to-dos real quick. 1:38 For this first to do, it says, create a new string named place and 1:41 assign it a value of your choosing. 1:45 For this example, I chose Kwik E Mart. 1:47 So then I provided you the console like we talked about. 1:49 And we want to prompt the user what is your first name and 1:53 store that in a new variable? 1:57 And then finally, we want a print out to the console, hello first name, 2:00 welcome to the, place that you chose, all using those variables. 2:03 This might seem like a fairly simple application, but 2:08 it's great practice in recalling the syntax and flow of the application. 2:11 If you can't quite get it, don't fret. 2:16 I show how I did it in the video right after this. 2:18 But please, do give it a try. 2:20 That struggle to remember the syntax and structure is well worth it. 2:22 That recall will pay off in the long run. 2:27 It's just like muscles. 2:29 No pain, no gain for your brain. 2:30 You got this. 2:33
