Refactorings – Introduce Parameter Object

The Introduce Parameter Object refactoring consolidates selected parameters into single object. If you frequently need to pass similar sets of values to methods that tend to be passed together, it might be useful to encapsulate these values into an object that carries all of this data. It is worthwhile to turn these parameters into objects just to group the data together. As the result, calling statements will become more compact and you will be able to add data processing logic to the newly declared object. This refactoring is also useful because it reduces the size of the parameter lists, and long parameter lists are hard to read and understand.
