The Solution

1:38 with Craig Dennis

This is how I solved it! How'd you do?

  • You might've noticed I used %n for new line, instead of the escape sequence \n. The reason for this is that Windows and Unix based systems (Like Mac and Linux) use different newline sequences. %n makes the proper distinction.

    Okay so how'd you do? 0:00
    Again, now don't worry if you had some sort of struggle. 0:02
    It's totally natural and you are growing and 0:05
    honing your skills through that process no matter what you were doing. 0:07
    So here's how I did it. 0:10
    So I needed to create a string named place, 0:11
    and the place I chose is called Kwik E Mart. 0:15
    So there we are, there's Kwik E Mart inside of a string literal. 0:18
    You can tell because I've got the double quotes there. 0:21
    And then I used the read line method. 0:23
    So that's off of the console, I used console I used the read line method. 0:27
    One thing I want to note here is see this L, it's capitalized, and 0:31
    that trips some people up sometimes they forget to capitalize that. 0:34
    It is camel-cased, it's read Line, two words, jammed together, camel cased. 0:36
    And I left a few spaces on it, too, so that it's all on the same line, right? 0:41
    And then finally, we used Print+F to print formatted text, right? 0:45
    And these %s's here are the placeholders that line up with firstName and place. 0:53
    I'm also using %n here. 0:57
    Check the teachers notes on this video for more on that. 1:00
    And then we can of course run it right, we can say clear && javac and again 1:05
    files called Greeter, I am gonna make sure I say that, don't forget to save. 1:11
    And we're going to run it. 1:14
    There is my JAVA_TOOL_OPTIONS. 1:23
    What is your first name? 1:26
    It's Craig. 1:27
    Hi, Craig. Welcome to Kwik E Mart. 1:28
    Great! 1:29
    How do you do? I wanna remind you, keep on practicing and 1:30
    make sure you let us know if you'd like to see more of these. 1:33
