This book I read to prepare for the IT School of Samsung, which has helped me in the future when developing “Travel Quest”. In it you can find all the basic knowledge of Java – the history of the language versions, the path of development and much more. After reading this book I was significantly easier to learn the native Android development and to develop their projects using Java. In each of the chapters are set out clear and accessible information about the different possibilities of this programming language. Overall, I liked the book, particularly memorable funny examples and illustrations to them.
