Welcome and thanks for stopping by.

is there any significant difference when approaching web testing as opposed to regular software testing? Do you have to look for other kinds of flaws or is code just code when it comes down to it?

Welcome guys and thank you so much for promoting your book here.
I have become rather interested in Go over the last year and am always looking for new study material.

That's a really good question, and I would say the answer is yes. The language, and especially the first language, has a big impact on the way you think about problem solving and computing. This book definitely helps students begin thinking like computer scientists, but clearly the more languages and experience people have the deeper their thinking will be.


Thank you!

Is there a difference between thinking like a computer scientist, when you are focusing on working with OOP languages like Java and thinking like a computer scientist focusing on languages better suited to other types of programming like Python? In other words, does the approach you take regarding languages and programming paradigms influence your thought processes?

Hi guys,

welcome and thank you for promoting your book here. It is already on my wishlist in case I am not one of the lucky winners.

OK; I exported the program and it works fine, no idea, why Eclipse has a problm with it.

Thanks, I got the absolute path, but it does not work either.

I tried:

File file = new File("C:\\Users\\Marcus\\workspace\\CharacterGenerator\\gui\\testfile.txt");


File file = new File("C:/Users/Marcus/workspace/CharacterGenerator/gui/testfile.txt");

Still, the system cannot find the path.

Thank you. Does not help either, and yes, I have a gui package.
Now Eclipse tells me it cannot find the path.

Hello all,

I am writing an RPG character generator and the "Save file" does not work, I always get a "file not found error" although the file stuff is written to exists and I have added a line to create a file if it does not exist.
All to no avail.
This is the code:

Hi and thank you for promoting the book here,

I have a question concerning Android and Augmented Reality:

Are there any features in Android that make it especially suitable for Augmented Reality applications compared to iOS or Windows Mobile? And if so, what are they?

Yes, Stefan, I am aware what this message means, yes, Stefan, I know there are other > in the code (because there are lots of > in HTML, I actually do a lot of HTML pushing in my day job) and my question was:

Is there a better and simple way to extract a substring?

because I am aware the one I have chosen does not work.

Hi all,

I want to extract a specific String from HTML, specifically, I want to extract a String from in between <...>

So far, I've got this

The problem I have is when I change the last parameter in this line:


i.e. the generic alternative, I get this error message:

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -366
at java.lang.String.substring(Unknown Source)
at main.HTMLGrabber.main(

Is there a better and simple way to extract a substring?

Thank you.
