What is a JSON File?
-----------------------------------
JSON stands for JavaScript Object Notation. JSON file contains,JSON Objects with .json file extension.
In this modern era, we have a lot of programming languages. Almost all of us use different web services in our daily life (Eg. Weather report, currency conversion, enquiring Gold rates, cricket scores).
Our browser is the point of contact, to make the request to the server, receive the response from the server, process the response and render it to the user. A web server may be implemented with any programing language like Java, python etc. Our browser can understand Javascript. So there has to be a common, language-independent data transmission between a web application and a web server.
What we will learn in this video:
1. Steps to read the JSON file
2. Typecasting in Java

I have a doubt while printing iterator.next(), will it print the value in first index, or it will start printing from 2nd as its next(),

To those who are getting error use String instead of long. We are getting correct output package extentproject; import java.io.FileReader; import java.io.IOException; import java.util.Iterator; import org.json.simple.JSONArray; import org.json.simple.JSONObject; import org.json.simple.parser.JSONParser; import org.json.simple.parser.ParseException; public class Classfilewriter { public static void main(String[] args) throws IOException, ParseException { JSONParser jsonparser = new JSONParser(); FileReader filereader = new FileReader("file.txt"); //we cannot directly read from jsonparser so we are converting to jsonobject Object parsedobject = jsonparser.parse(filereader); JSONObject jsonobject = (JSONObject) parsedobject; String name = (String) jsonobject.get("name"); String age = (String) jsonobject.get("age"); JSONArray array = (JSONArray) jsonobject.get("qualities"); Iterator iterator = array.iterator(); System.out.println(name); System.out.println(age); while((iterator.hasNext())) { System.out.println(iterator.next()); } } } Output: testing 5 magical memories testing memories

@mushekfahath9245 2 года назад

Instead of All those type casting, why can't we store the data into Object return type.. brother ?!?

@LearnAutomationOnline 2 года назад

Yeah we can do that as well. I don't what I was thinking at that time. If u see the latest rest assured tutorials, I would have stored in objects.

Make sure your json file is valid. Use websites like jsonlint to ensure your json is valid

Arul, as a begginer( 3years L2 support experience), 3 years gap due to marriage and kid, after a break i need to try for Testing role as i can get plenty of option. in which part and all i need to concentrate? or i need to learn all your videos?

@LearnAutomationOnline 4 года назад

Considering the current competition in the job market, it's wiser to master most of the things with respect to test automation. I would suggest you to be thorough, I mean THOROUGH with selenium, TestNG, github, rest API, libraries like unirest or rest assured, cucumber, page object model, java collection concepts and Jenkins. Remaining all will be nice to have. Feel free to ping or comment in case you need further clarifications.

@7.55 - What is the difference between primitive data type & class?

@LearnAutomationOnline 5 лет назад

Primitive data types and classes are not comparable one. A wrapper class is just like any other java class, provided to give the support for all the primitive data types java was supporting inorder to make it more object oriented.

Bro, I want to register a company with different roles. Role is like electronic, mechanical, I have 12 roles. At one time or immediately I want to register. How to test different roles using JSON with selenium. Can you please. Or data driven . Please make a video for this. My case I real time scenario. How to execute 12 times with different roles.

@LearnAutomationOnline 4 года назад

For this case you should not use, selenium. You should be focusing on the registration API, with the JSON body. You have to discuss with the developer of the application to get the API for that.

sir, I have a doubt, can we use List to store multiple values of "special quality" instead of JSONArray, why do we go for JSON Array, Is there any specific reasons?

@LearnAutomationOnline Год назад

List can store any type of data.
