What are the scenarios for using the Java Builder patte…

The use cases of the Java Builder pattern include:

1. Creating complex objects: When the process of creating an object is complicated, involving multiple steps or requiring multiple parameters, the builder pattern can be used to simplify the object creation process.
2. The object that needs to be created includes multiple optional parameters: The Builder pattern allows for easy setting of the object’s optional parameters, only needing to set the required parameters, rather than setting all parameters.
3. The object that needs to be created is an immutable object: the Builder pattern can ensure that the created object is immutable, meaning its properties cannot be changed.
4. The object that needs to be created has a complex internal structure: the Builder pattern can encapsulate the creation process, making it transparent to the client, while also hiding the complex internal structure of the object.
5. The creation process of the object that needs to be created requires multiple configurations, using the builder pattern allows for multiple configurations to be done through chained calls, making the configuration process more flexible and convenient.

In conclusion, the builder pattern is suitable for scenarios where complex objects need to be created, multiple configurations are needed, or immutable objects need to be created.
