What would you expect it to do?

Re: I was just about to start and it has problems?
I was just gonna make something where you type in a word and it tells you what it means but all im trying to do is test the scanner and it doesn't even do that
Re: I was just about to start and it has problems?
How are you testing a Scanner?
All this code does is create a Scanner. You don't actually tell the Scanner to do anything, and you don't print anything to the console, which is why you don't see anything when the program executes.
Try adding a simple print statement at the very end of your main() method, that way you at least know it's running.

Re: I was just about to start and it has problems?
the text appears but it just skips right over the scanner and prints it
import java.util.Scanner;
public class data {
public static void main(String args[]){
Scanner input = new Scanner (System.in);
System.out.println("hello world");
}
}
Re: I was just about to start and it has problems?
Scanner is just an object. You haven't called any of its methods to have it do anything.
Re: I was just about to start and it has problems?
ive used this line before and it let me type in but its not this time literally just Scanner input = new Scanner(system.in); and it let me type in
Re: I was just about to start and it has problems?
Try something like
String s= input.next(); System.out.println(s);
after your hello world print statement
