Apex Wrapper Classes are custom classes in Salesforce that are used to hold one or more primitive data types as members. This allows for encapsulating multiple data elements into a single unit, making it easier to manipulate, organize, and pass data between different parts of a Salesforce application.
Wrapper classes can be particularly useful when working with complex data structures or data from external sources. They provide a way to manage data in a structured and organized manner, making it easier to access and modify.
Here are some of the key benefits of using Apex Wrapper Classes:
- Encapsulation: Wrapper classes allow for encapsulating multiple data elements into a single unit, making it easier to manipulate, organize, and pass data between different parts of a Salesforce application.
- Data Organization: Wrapper classes provide a way to manage data in a structured and organized manner, making it easier to access and modify.
- Reusability: Wrapper classes can be used in multiple parts of a Salesforce application, making it easier to reuse the same data structures across different parts of the application.
- Improved Performance: Wrapper classes can improve the performance of Salesforce applications by reducing the number of database queries required to access data.

To create an Apex Wrapper Class, you need to define a custom class with the desired properties and methods. You can then create instances of the custom class and use them to store and manipulate data in your Salesforce application.
In conclusion, Apex Wrapper Classes are a powerful and flexible tool for managing data in Salesforce. By encapsulating multiple data elements into a single unit and providing a structured and organized way to access and manipulate data, Wrapper Classes can help you build more efficient and effective Salesforce applications.
It's also worth noting that wrapper classes can be used in conjunction with other data types, such as maps, lists, and sets, to provide even more flexibility when working with data. For example, you could use a list of wrapper classes to store a collection of objects, or a map of wrapper classes to store a collection of objects with a specific key.
In conclusion, wrapper classes in Apex are an incredibly useful tool for Salesforce developers. They provide a way of encapsulating data in an object-oriented manner, allowing developers to create custom objects that can be manipulated and passed around as single entities. Whether you're working with dynamic data, managing large amounts of data, or simply need to pass data between methods and controllers, wrapper classes are an essential tool for Salesforce development.
