New to Java

I am experiment with the java.util.scanner API after compiling the code below I received the following error:

The import "java.util.Scanner" is not valid, since it does not name a type in a package.

I declared a string variable should that suffice?



import java.util.Scanner;

public class Echo {

public static void main (String[] args)
{
String message;
Scanner scan = new Scanner (System.in);

System.out.println ("enter something:");

message = scan.nextLine();

System.out.println ("hey you entered: \"" + message + "\"");

}

}
