REST API Automation Testing from Scratch - REST Assured Java - Building POJO Classes to Construct JSON Payload to API

The video tutorial guides viewers through building Java classes to handle JSON data. It covers creating base and nested classes, understanding JSON structure, and generating getters and setters. The tutorial emphasizes the importance of matching JSON keys with class variables and demonstrates how to handle arrays and nested JSON objects. By the end, viewers will know how to create Java objects from JSON data and prepare them for API integration.

What is the primary purpose of creating getters and setters in a Java class?

• To directly access and modify class variables

• To delete class variables

• To provide controlled access to class variables

• To initialize class variables

In the context of JSON, what does a nested JSON object require in Java?

• A separate method

• A subclass

• A static variable

• A constant

Which data type is used for a JSON key that holds a number without quotes?

• Boolean

• Integer

• Double

• String

How should a JSON array be represented in a Java class?

• As a List of Strings

• As a Set

• As a Map

• As a single String

What is the correct return type for a JSON key that contains another JSON object?

• String

• Integer

• The class representing the nested JSON

• Boolean

Why is it important to match the key names in JSON with variable names in Java?

• To maintain consistency and avoid errors

• To ensure the program compiles

• To prevent runtime errors

• To improve performance

What is the advantage of using a 'double' data type for latitude and longitude?

• It can store negative values and decimals

• It is more secure

• It is faster to process

• It uses less memory

What is the purpose of generating getters and setters after defining class variables?

• To provide a user interface

• To initialize the variables

• To allow controlled access and modification

• To compile the code

What should be done if a JSON key is an array of multiple items?

• Use a single String variable

• Use a Set

• Use a Map

• Use a List of Strings

What is the final step before sending a Java object to an API?

• Compile the code

• Set values using setter methods

• Create a new class

• Delete unused variables
