Builder Pattern in Salesforce

In Salesforce, the Builder pattern is implemented using Apex, the platform’s programming language, to construct complex objects like custom records or dynamic queries systematically. A typical example involves creating a custom object record, such as `CustomObject__c`, with multiple fields. The `CustomObjectBuilder` class serves as a builder, facilitating the step-by-step construction of the object. It employs a fluent interface, allowing developers to set various field values using methods like `withField1`, `withField2`, etc.

 The builder initializes the object and culminates with the `build` method, returning the fully constructed `CustomObject__c` instance. This approach enhances code readability, especially for objects with numerous fields, and offers flexibility for future modifications without altering client code. Ultimately, the Builder pattern in Salesforce provides an organized and extensible way to create complex objects in a more modular and maintainable manner.
