Preface

This is a page from the book titled The json-simple Java Library . The book explains how to use the json-simple Java library to generate, transform, and query JSON text. This page provides review questionsand answers for the page titled Json0200 The What and Why of JSON . Once you study that page, you should be able to answer the review questions in this page.

The questions and the answers in this page are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.

The Figures and Listings (if any) are grouped together. It is recommend that when a question or an answer refers to a Figure or a Listing, that you open it in a new window tomake it easy to view it while reading the question or the answer.

Answers

Answer 8

False. This book is not intended to teach you about JSON. There are numerous tutorials on the web that you can access for that purpose. This book is intendedto teach you how to use the json-simple Java library, (which is one of several available libraries), to parse, generate, transform, and query JSON.

Go back to Question 8

Answer 7

True. According to the InfoWorld article of August 25, 2014, "Several NoSQL databases -- including the wildly successful MongoDB and Couchbase -- store data in JSON documents natively."

Answer 6

True.

Go back to Question 6

Answer 5

False. According to the online document titled Java API for JSON Processing: An Introduction to JSON , "JSON can represent two structured types: objects and arrays. An object is an unordered collection ofzero or more name/value pairs. An array is an ordered sequence of zero or more values. The values can be strings, numbers, booleans, null, and these twostructured types."

Go back to Question 5

Answer 4

False. It is important to note that even though JSON is based on JavaScript syntax, JASON is not JavaScript nor is it any other programming language. Infact, it is not a programming language at all. JSON is simply "a lightweight, text-based, language-independent data exchange format" -- nothing more and nothing less.

Go back to Question 4

Answer 3

False. Visual Basic is not based on the C-family of languages. Visual Basic is based on the BASIC programming language that came into existence in 1964. The C programming language came into existence independently in 1972.

Answer 2

True.

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
