How would I read data from a csv file into an array of objects in Java?

The Array of objects should be called People

So in this case I want the first 3 records to be in order of: name, age, id

e.g:

Jeff, 19, 1

Mark, 12, 2

Holly, 15, 3

I want the above to go into the Peoples array of object slot as: People[0], People[1], People[2]

And then I want the next three records in the csv file to be in the order of just name and age

e.g:

Ben, 20

Jake, 22

Mel, 24

I want the above to go into the Peoples array of object slot as: People[3], People[4], People[5]
