How do you handle a null response in JSON
You can instruct Jackson to ignore a field while converting a Java object to JSON if it is null at the field level by using the annotation @JsonInclude(Include. NON_NULL) or at the class level by using @JsonInclude(Include. NON_NULL) to only include non-null fields, thereby excluding any attribute whose value is null.
Does JSON have undefined
If any of these values are encountered during conversion, they are either omitted (when found in an object) or changed to null (when found in an array), as they are not valid JSON values.

How do you handle null values in JSON response in Java
Check if the array is empty using basic Java rules; if the array doesnt exist and you try to get it, it just returns null; handle it; stop parsing if you know it will fail.

What is the difference between JSON and Yaml
Since YAML is a superset of JSON, it can parse JSON with a YAML parser.
Differences between YAML and JSON are:
|String quotes are optional but it supports single and double quotes.||Strings must be in double quotes.|
|Root node can be any of the valid data types.||Root node must either be an array or an object.|
What is the data type of JSON
A string, a number, an object (JSON object), and an array are valid data types.
How is relational structure different than JSON
JSON is a great data format because it is straightforward, lightweight, and perfect for passing around raw data in a very basic format with a syntax suitable for storing and exchanging text data. A relational database makes sense for quick and effective storage and retrieval of data that has relational properties.

Can JSON parse return undefined
JSON accepts null and empty strings ( ) as values, but it does not accept undefined as a valid value. Therefore, we must manually add null to the JSON object in order to parse undefined values.
Does JSON Stringify remove undefined
All object attributes that are undefined will be excluded by JSON. stringify.
Is null valid JSON
This means that with RFC 7159, “null” (as well as “true” and “false”) becomes a valid JSON text and that the JSON text serialized value of a null object is indeed “null.” One of the changes in RFC 7159 is that a JSON text is no longer defined as being an object or an array but rather as being a serialized value.
