I'm looking at some code that I may use in my program to look up a customers ID number and I want to do a search to check if the number is in the file before it tries to return the ID and customers info. I know <T> but I didn't know it could be used for other things like <Video> Can someone explain what is going on in this set of code? I mainly want to know how one would <random thing> make that work and what it does.
