I NEED SOME ASSISTANCE. IVE ATTACHED MY CODE,THE CODE PROMPT, TEXT FILE. CAN YOU TELL ME WHAT I NEED TO FIX/ADD/CHANGE TO MAKE THE CODE WORK. I ALSO NEED HELP WITH HAVING MY CODE READ THE DEVICES FROM THE TEXT FILE.

"Config file. txt"

Code Prompt

Suppose you are writing a program to test the components of the devices. The components we are interested in are displays, batteries, and processors. These components are different in different device. Each device has its own program for testing these components. To know which test to run, you will need to instantiate objects that correspond to each one of the components.

We assume that device to be tested are stored in a configuration file (text file). Because this situation fits the Abstract Factory pattern so well, you can use that pattern to organize the creation of objects that correspond to each device. You will also need to use the variation of singleton pattern to ensure that at most two instances of each device in each test run. Please note finishing running all devicesspecified in the configuration file is considered as one test run.
