Hello,

On the wickedlysmart.com website I could download a pdf with the Sharpen your pencil solutions but the pdf stops at chapter 8.

Does anybody has the full Sharpen your pencil solutions with all the chapters?

thanks in advance.

Welcome to the Ranch

We don't approve of handing out "free" material. You would do better to work out the solutions for yourself, and you should show us what you have got, then we can agree or disagree.
And make sure to tell us the page numbers, so we can find the puzzles.

Thank you. And sorry for my mistake which I told you about yesterday.

I have had a look in the book:
p 248 no answers in book, but it looks like code you can execute.
p 285 no answer in book; the code can be compiled (or not compiled) and executed.
p 328 no answer in book: by creating an Exception class you can run the code and put lots of print statements in.
p 334 no answer in book: requires drawing abilities for a class hierarchy.
p 362 no answers in book: a look through the API will give hints.
p 392 no answer in book: requires you to write javadoc and other comments.
p 465 no anwers in book: needs a look at those classes in the API.
p 482 no answers in book You will have to be creative with a pencil
p 554-5 answers p 577-8

Hi Daniel,

If you are just starting out, I encourage you to turn off the IDE and instead learn how to write code using a simple text editor with the native javac and java command line compiler and application. While an IDE might appear to make your life easier, it can make you reliant on it if you don't know the basics. Think back to when you first started to learn to add and subtract - image how little you would have learned if the teacher let you use a calculator. Using an IDE is similar.

But, don't just take this simple Ranch Hand's word for it. You can read similar opinions from most of the Sheriffs and Bartenders in this thread.
