Wow Laugh | :laugh: What a story. I was so angry at Hortsmann that I wanted to write to him email as well, but I didn't want to be mean... so I didn't Poke tongue | ;-P But sometimes when I read those books I have the same feeling like... Is he that bad at expalining or he simply can't do that himself? Because I understand that some books can be hard to learn from, because they are maybe too advanced or maybe too boring or maybe badly explained but still they have an explanation, they communicate something but some books, and especially this... well... the information is simply not there (!). Even if I find something hard to understand I read it all over again but in this book... I can't read it again because there is nothing to unerstand, because the information is absent. For example he writes a code like this:

public void paintComponent(Graphics g) {

var g2 = (Graphics2D) g;
...

}

Than he never uses this method and I have no clue what to put into g parameter if I guess I use it in main? Other classes don't never use this method either... and where this g2 come from? Where did he crate an object of this unkown class. "var" doesn't say anything to me so I have no clue, what this class is and he doesn't reveal that either in his book.... And than he writes something like:

Image image = new ImageIcon(filename).getImage();

My comment: And again this mysterious method with that mysterious g which is casted from g2, that I don't know where to put instead if I would to use it in main just to see how that works...


public void paintComponent(Graphics g) {

g.drawImage(mage, x,y,null);

My comment: And where do I get this g from ... I don't get anything Sigh | :sigh: How did that happen and where was that mysterious g created? Of course if I want to use it... again, I guess in main or anywhere... but where is this g-object created so I can put it in the parameter and use this method? Laugh | :laugh: what da... OMG | :OMG:
...

}

And I own plenty of books like this Smile | :) Do you understand my frustration now? Laugh | :laugh:

When building an application, when is the most important time to consider the User Experience?
They are the ones we write code for, right?
