The code is available as a Gradle project that may be used by:

• Running Gradle commands in a terminal

• Importing in Eclipse (with limitations)

• Importing in IntelliJ

There are two ways to download this project.You may:

• Click on the Download ZIP button on the project page to download a ZIP archive, then unzip it in the directory of your choice

• Or you can clone the project using Git, in order to be able to update it easily when modifications or additions are made. For this, you will need to have Git installed on your PC and use the URL available on this page in the SSH clone URL area.

IntelliJ offers the best support for Kotlin development, plus full Gradle integration.If you don’t have IntelliJ, just download the Community version from the JetBrains site.This free version has all you need for using the examples and solving the exercises in the book.

To import the project into IntelliJ:

• open the File menu and select New > Project from existing sources.

• In the file chooser dialog box, select the fpinkotlin-parent directory and click OK

• in the new dialog box, check the Import project from external model option, select Gradle and click _Next to get the following dialog box:

• Click Finish and wait until import is complete

Running a test

If you do not want to use IntelliJ, you can use any text editor to create an implementation for an exercise.Then you can run the corresponding test using Gradle from the command line.If you chose this solution, I suppose you will already have Gradle setup.If not, just download the current version from the Gradle site and install it.

For each chapter, you will find two modules called chaptername-exercises and chaptername-solutions . Go to the first exercise in the src/main/kotlin hierarchy.Here, you will find some code with either a comment saying "To be implemented" or function(s) with the implementation replaced with a single line throwing a runtime exception.Just implement the missing code.

Note that code is often duplicated from one exercise to the another, so you should not look at the code for exercise 2 before doing exercise 1, since exercise 2 will often contain the solution to exercise one.

If you don’t find the correct solution to an exercise, you can look at the corresponding chaptername-solutions module.You may run the solution test to verify that the solution is working.

Code modules are generally named after the chapter titles, and not the chapter numbers, which sometimes make them difficult to find.Here is the list of the modules:

• Chapter 1: fpinkotlin-introduction

• Chapter 2: This chapter has no corresponding module

• Chapter 3: fpinkotlin-functions

• Chapter 4: fpinkotlin-recursion

• Chapter 5: fpinkotlin-lists

• Chapter 6: fpinkotlin-optionaldata

• Chapter 7: fpinkotlin-handlingerrors

• Chapter 8: fpinkotlin-advancedlisthandling

• Chapter 9: fpinkotlin-Workingwithlaziness

• Chapter 10: fpinkotlin-trees

• Chapter 11: fpinkotlin-advancedtrees

• Chapter 12: fpinkotlin-effects

• Chapter 13: fpinkotlin-actors

• Chapter 14: fpinkotlin-commonproblems

The code examples for appendix A & B are to be found in the kotlingradle repository
