Builder

The Builder pattern makes call sites clearer and more precise. The Builder pattern supports the step-by-step construction of complex objects. Builder assembles an object incrementally through well-defined steps rather than through a single constructor call with many parameters. The Builder pattern lets each field be set explicitly and in any order. Builder is useful when an object has many optional components or configuration details, and different configurations need to be produced using the same construction process. The Builder pattern is presented as a fix for methods with optional or variable parameters.
