i'm assuming you're reading in input line line.

you can use string.split() accomplish (the first part of) trying do.

for example, following code

string s1 = "michael | straham | eng101(4.0) | mth303"; char[] separators = { '|' }; string[] values = s1.split(separators); 

would give array of 4 strings ( "michael", "straham", "eng101(4.0)", "mth303"). can analyze values array see in class. i'd have code looks (in pseudocode):

foreach (line in input) {      string s1 = line;     char[] separators = { '|' };     string[] values = s1.split(separators);      string firstname = values[0];     string lastname = values[1];      (i = 2, < values.length)     {         if (values[i] looks "eng101")         {            add firstname lastname "eng101" student list         }         else if (values[i] looks "mth303")         {            ....         }         ....     } }
