Let’s be honest—most of us have been using Windows since we were kids. It’s the backbone of the corporate world and feels like the default choice for every computer user. For years, I thought it was the only real option. But what if I told you there isn't just an "alternative" out there, but a genuine upgrade? When people talk about switching to Linux , it can feel overwhelming because there are so many versions. However, I want to talk specifically about Ubuntu .
In Apex, if you deserialize JSON data into an object, you can access its members using dot notation or square bracket notation, just like accessing any other object's properties. Here's an example of how to do it:
Let's say you have the following JSON data representing an object with members:
String jsonData = '{"name": "John", "age": 30}';
You can deserialize it into an object like this:
// Define a class to represent the structure of the JSON object
public class Person {
public String name;
public Integer age;
}
// Deserialize the JSON into the Person object
Person personObject = (Person)JSON.deserialize(jsonData, Person.class);
Now you can access the members of the `personObject` using dot notation:
String personName = personObject.name; // "John"
Integer personAge = personObject.age; // 30
Or, you can use square bracket notation to access the members:
String personName = (String)personObject.get('name'); // "John"
Integer personAge = (Integer)personObject.get('age'); // 30
Both dot notation and square bracket notation will give you the same result. However, dot notation is more concise and often preferred when you know the specific member names and their data types. Square bracket notation is more useful when you have dynamic member names or when you are iterating over the keys of the object.
