How you know the 10th item gets selected when you click on 2th item ? Are they changing the background color to yellow too ?
Check the position value, are the position value printed is same as the position you clicked?

Congratulations !

Congratulations!

You made a statement that a method should not contain more than five lines (excluding opening and closing brackets) and the title of your book reflects that. Why do you think five lines are enough for a single method?

There a very good explanation in 3.1. Our First Rule, Why Five Lines

Thanks Campbell

Hi Jean-Georges Perrin,

As the book said, it cover three programming languages, which are Java, Scala and Python.

From your experience,  what should be considered when choosing a language for Spark ? Does they have pros and cons of each ?

Thanks.
