Reading from a CSV file into an array

I am making a program that has an array of people. The people have different amounts of info for instance they all have a first name, last name, type, gender. The first issue I have is some also have email and some have a image (using Icon) and some have both of them.

I need to read these pieces of data in and then display them, it is for a college class and the teacher was basically like figure it out.. I have read the API and numerous articles and can't seem to get it to work. Can someone give me a push in the right direction?

I am not looking for you to hand me the answers just a little help.

Read the file line by line and split line with ,. // you need to create a pojo to hold all the user info.

List<UserObject> users = new ArrayList<UserObject>();
try {
    br = new BufferedReader(new FileReader(csvFile));
    while ((line = br.readLine()) != null) {
         String[] userinfos = line.split(",");
         UserObject newUser = new UserObject();
         //set the mandatory attributes here 
         if (userinfos.length > 4) {
             // you have the extra fields here.
             // set the extra fields to user here
         }
         users.add(newUser);
    }

} catch (FileNotFoundException e) {
     e.printStackTrace();
}

One problem with this is first name or last name might have commas with in them. I suggest you to use any third party csv parser like Open Csv.
