Hello, this program is to be coded in purely Java, using Jdk 11 on Windows or Debian. This is a simple program which takes of certain variables through commandline and/or a text file, stores them using arraylists and a simple hashmap, and prompts users to run certain commands to display and store the variables. The details are attached in the files below. I have already created the base program, which does most of the work; all you need to do is add and extend to my files according to the “exercises” attached alongside it. It is a simple enough program but unfortunately I do not have the time to complete this; thank you for your time.
