Design mode 8 ——– filter mode


Filter mode

Filter pattern or criteria pattern is a design pattern that allows developers to filter a set of objects using different standards and connect them in a decoupled way through logical operations. This type of design pattern belongs to structural pattern, which combines multiple standards to obtain a single standard.


We will create a person object, the criteria interface, and the entity class that implements the interface to filter the list of person objects. Criteriapatterndemo, our demo class uses criteria objects to filter the list of person objects based on various standards and their combination.
