Help with simple text game...

**iansmiler** · May 23rd, 2012, 02:39 PM

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.

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:
