    Question User input error help.

    Alright so basically today I decided I wanted to learn Java as it has been on my to do list for about 6 months now and basically I asked a few friends who knew how to program and they redirected me to thenewboston's tutorials on java programming. Everything was going smooth for awhile I was understanding everything he said and I was taking notes and such and then I got on to his user input tutorial. Now I listened to what he said, took notes on what he said what this and that did, and typed in what he wrote down. Now what happened whenever I ran it on Eclipse is that it gave me this error message.Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method nextline() is undefined for the type Scanner at apples.main(apples.java:6)Could someone please help on what I should do. The code to what I'm trying to use to get user input is this....
    import java.util.Scanner;

    public class apples{
    public static void main(String args[]){
    Scanner bucky = new Scanner(System.in);
    System.out.println(bucky.nextline());
    }
    }

    your bucky.nextline

    should be

    bucky.nextLine

    notice the capitol L in line

    then when you run it type some word like hi in the console then it will return the word in the println

    As an aside if you're like me you'll make lots of typos as you learn a new technology. "The method whatever() is undefined etc" is common indication by the compiler of a typo.

    The API documentation is very useful here. Click "Scanner" on the left and you will get the documentation for this class. From there you can check both the spelling and the number and types of arguments that the method takes. (The other common cause of this particular compiler message). It's never too soon to have the documentation open as you code, to get a better idea of what's happening and to round out the commentary in the videos.
