Question

Ok so this is probably a very beginner question but…

Right now I have an object called Person with a method on it called setName

I am in my main class and I have declared

List People = new LinkedList();

What I want to do is simply call the setName function of the object in the first position.
I have found that this is very easy to do when working with an array of People. All I would do would be to say

People[0].setName("steve");

But since it is in a linkedlist I am having troubles.

I tried using the “get” method like so…

People.get(0)

but then it doesn’t allow me to use my user defined methods so I can’t set the name.

What is the best way to get an object out of a linked list and access its methods and instance variables?

thanks in advance

Answer 1

You want to use generics to make it a list of people:

List<Person> People = new LinkedList<Person>();

People.get(0).setName("steve");
