Hi

I am currently learning Java, for my own interest, and am still very much a Newbie. I am interested if you think that the Cucumber book would help me to commission work ie the customer with the wild idea, so that I can better refine and describe what it is I want or is it specifically aimed at devs.

Many thanks

Rob

I will have another look and try to work it out, I think the biggest problem is I don't know exactly what the code is doing as you have just explained very clearly, many thanks.

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 7
at Puzzle4.main(Puzzle4.java:22)


I have tried removing the curly bracket and it throws another error,

eclipse has no crosses in the code so I am at a loss.

thank you for your help.

Hi,

I am working my way through the Head first Java book and can't work out why the following code won't compile, is it a typo in the book?

public class Puzzle4 { public static void main(String [] args) { Puzzle4b[] obs= new Puzzle4b[6]; int y = 1; int x = 0; int result = 0; while (x < 6) { obs [x] = new Puzzle4b(); obs[x].ivar = y; y = y * 10; x = x + 1; } x = 6; while (x > 0) { x = x + 1; result = result + obs[x].doStuff(x); } System.out.println("result " + result); } } class Puzzle4b { int ivar; public int doStuff (int factor) { if (ivar > 100) { return ivar*factor; } else { return ivar*(5 - factor); } } }

I am using Eclipse.

Many thanks

Silly mistake, thank you.

MooseGreetings.java

Thought I should post my code.

public class MooseGreeting {
public static void main(String[] args) {
System.out.println("moooooooo");
}
}

Really new to this and don't really understand what it says.

Sorry to be a pain

Hi,

I realise that this will have come up before but I am not sure what to search for.

I have installed Java 1.6.0_24 and set my Paths (I think) I have followed the instructions for Moose Greetings (https://coderanch.com/how-to/java/how-to-create-java-program) When I compile I get an error stating:

MooseGreetings.java:1: class MooseGreeting is public, should be declared in a file named MooseGreeting.java
public class MooseGreeting {


Please could someone let me know what I am doing wrong, the text was copied from the webpage.

Many thanks
