Answer 1

In order to achieve this, there are the following things you need to do:

Open the file for reading (this part you have done)
Start a loop (until end-of-file is reached), and inside that loop:
  Read a line from the file
  Format the line (using the space character as a separator) in order to find the three different kinds of information.
  Add the mentioned information in the structure you have created.
  Put the mentioned structure in a collection.
Close the file

About how to read files and how to format strings, containing separators, there are plenty of examples to be found on the internet and on this site.
