Collection: searching, deleting and sorting

Question

Hi,
I have a text file in which has the data:
Name (String), Age (int), Sex (char), Height (double)
e.g.
John, 34, M, 150.6 (line 1)
David, 54, M, 177.8 (line 2)
There are many records in a text file. And the printout should like:
Name: John
Age: 34
Sex: M
Height: 150.6
Not just display the whole line. I need the tokens to be displayed one by one on console screen.
How can I use Collection framework, such as Vector() to do it?
Please advise.

You can read in the file using a FileReader, then parse each line with a StringTokenizer.
I would recommend introducing a class Person to capture the 4 types of data, and then add each Person to a List (yes, this is from the Collections framework).
Some small snippets:FileReader inputFile = new FileReader("myfile.txt");
List persons = new ArrayList();
while(....) {
String line = inputFile.readLine();
StringTokenizer strtok = new StringTokenizer(",");
Person p = new Person(name, age, sex, height);
persons.add(p);
System.out.println("Name: " + p.getName());
// do something with the list here
