Read each line using buffered reader and then do that:

HashMap<String, String> values = new HashMap<String, String>;

// read the line here
String line = ...;
String strings[] = line.split(" ");
String designation = strings[3];
values.put(strings[0], strings[1], strings[2]);

  • Read the file line by line
  • call String.split to split the different informations into an array
  • You can store these information in a Map whose key would be the username vinoth and values would be the array you just received from String.split
  • Even better you store these informations in an object that represents something with the properties you'd like.

  • Use String.substring(start, end) to get the relevant part of the line.
  • Call trim() on it.
