Another utility class that users will need to build is the file I/O class. This is a static Java class that contains all the methods for reading, writing, and deleting files, copying files, renaming files, accessing property files, finding files, setting file paths, extracting data, looking up messages, and many more. Storing all these similar methods in one central location for all CRUD operations (create, read, update, and delete) allows users to call these static methods from any page object or test class. Some of the more common methods will be outlined in this section.
