And you can actually understand that section That means you can use arithmetical operators on chars and actually get them to work.

David Tony Docherty Bartender Posts: 3005 59 posted 2 years ago firstly I'd like to say that Programming is bl**dy rewarding when something finally works!!! ... I believe it is the only package that is. (Can anyone confirm?) Apologies for all of those questions Knute I just what to ensure I understand, No apology necessary. They tell the compile of which kind of Scanner you are about to use, because the Scanner here is undefined by anyone. Error Cannot Find Symbol Class Googleplayservicesclient Tomorrow I would like to see where else in the program I can declare the reference variables other than main.

I think you know that it returns a String. posted 2 years ago I think I agree with the Head First book that you should stick with a text editor for now. Is this what makes programming addictive for most people? posted 2 years ago p.s.

Java can't find selction because variable name is selection. My adviser wants to use my code for a spin-off, but I want to use it for my own company Converting SCART to VGA/Jack A Riddle of Feelings Find the limit Consider the following program: public class Test public static void main(String[] args) { my_method(); } public static void my_method() { System.out.println("Hello, world!") } } 2 errors found: File: Test.java [line: 1] without having to say String.CharAt(0) first or import?

Your spelling mistakes don't seem to be a typo. Do you think that I've used the correct OO approach in the program? It actually puts a red line under this:Scanner scan = new Scanner(System.in);The semester is almost over and i need to find a solution to the compiling and running so i can You don't get to understand all the details as the IDE is hiding many of them from you.

As this is pretty much the first program I've ever written, I decided to write a program to ask for two integers and add them both together and then present them However, cases can also arise where it is clear to us that one of the cases has to be reached and therefore the error should not happen.

Also could you please expand upon what you mean by the following A char is not a character or anything; it is a number I've read "A Literal is the source A Riddle of Feelings Converting SCART to VGA/Jack Why was Gilderoy Lockhart unable to be cured?
