Best method for creating a collection.

Question

hi,
i've written a loop which specifies the content of a name,age and location String for each time it goes through the loop.
I've also created a Person() class which has the ability to set these strings as its variables.
What would be the best collection to use for putting together lots of Person() objects each with their own variables(set by the loop).
I've tried using an Person[] and using the variable i to set a person for each location for example
person [] people = new person[100]
int i = 0
public void loadPeople()
for(i = 0; i < 100; i++){
name = //Changing variable read from text file;
age = //changing variable read from text file;
location = //changing variable read from text file;
people[i] = new Person(name, age, location);
}however if i use the method
System.out.println("people[1].name");i get "null"; and name is definately public.
So i was wondering basically if there is something else a little better to use as a collection.
Thanks
Richard.

I bet the constructor looks amazingly similar to this:
public Person(String name, int age, String location)
  name = name;
  age = age;
  location = location;

Am I right?
If so, think about what this means.
name = name;
Assigns the value of a variable to itself. Not terribly useful, huh?
How about this instead?
this.name = name;
Assigns the value of the local name parameter to the attribute named 'name' of this object.
