    Question Help with simple text game...

    Hello gang,

    I am looking for some direction - I can program but I am an industrial Engineer and so I program Electronics such as PICs and also lots of PLC Software... I have no Java experience but I used to be quite good with Fortran!

    My son has come home from school and he wants to build a decision based text game and so I have committed to assist him build it in Java >.< So I need some pointers - I will be using Netbeans and have a rough understanding of the bare bones of a simple Java program (Hello World!!)

    So here is my first question:

    I would like to print one of several responses onto the screen based on an answer that I give to a question ie.

    Question: You have entered a room, there are 3 doors please choose a door to enter: a) Door to the left, b) Door straight ahead, c) Door to the right

    I then input a, b or c and then some text will be printed to the screen.

    Please help - Ian

    You're going to need a way of writing lines on the console, which comes for free with System.out - it's an object of type java.io.PrintStream, so you can println(String) to write some text onto the console followed by a newline. Next up, you'll need to read a line (the easiest way) of input from the user. That's not quite so easy, so open wide for some spoonfeeding: "new java.io.BufferedReader(new java.io.InputStreamReader(System.in)).readLine()"* will return a String object that will hold what the user entered, without the newline.

    Do you have access to the Java SE API documentation? There's a lot to read, but it's well worth reading. Start with the words in CamelCase above.
    Java Platform SE 6

    *I think the kids on the lawn outside may all be using Console.readLine() and Console.writer().println() nowadays.

    Question Re: Help with simple text game...

    Okay - this is what I got to so far:

    package text.project;
     
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    /**
     *
     * @author Ian Smith
     */
    public class TextProject {
     
        /**
         * @param args the command line arguments
         */
        public static void main(String[] args) {
            System.out.print("Enter your name and press Enter: ");
           BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
           String name = null;
           try {
             name = br.readLine();
           } catch (IOException e) {
             System.out.println("Error!");
             System.exit(1);
           }
           System.out.println("Your name is " + name);
        }
    }

    Now I want to put some if statements in - but I don't know how to go about it!!! Any help appreciated as always - Ian

    Please use highlight tags when posting code.

    You're going to want to get into the habit of checking the basic tutorials before asking a question- it's faster for you, and it's easier to help you when you get stuck or have a specific question than it is to answer "how do I do this" type questions.

    Always use Exception.printStackTrace() in place of print("An error occurred!"). Java if statements look like
    if ("Ian".equals(name))
      System.out.println("Sifu");
    else
      System.out.println("Hello, " + name);

    Java has better help for this sort of thing than I can give you:
