Thread: ArrayList Help

Hello Everyone,

I am having major problems with my code and I was wondering if someone could please help me out because I have been trying for a very long time to fix the problems, but really have no clue what to do. I am trying to write a program where members of a team each have a certain number of points ,but then they each get a percentage of their points deducted based on a formula. I already calculated how much each teammate gets deducted in a class and used a helper method called deduction(). Now, I want to put each teammate in an array list and have the deductions of each teammate in the array list. I then want the deductions to be added together to give me the total deductions of the team. However, I really don't know how to use array lists. Can anybody PLEASE help me?

import java.util.ArrayList;
 
public class Team {
 
	ArrayList Teammember = new ArrayList();
 
 
 
	public void teammemb(points teammember) {
 
		Teammmember.add("mark");
		Teammember.add("kevin");
		Teammember.add("keith");
		Teammember.add("eric");
 
		team bluebirds = new team bluebirds;
 
 
	}
 
	public double totalDeductions() {
		for(int i = 0; i < Teammember.size(); i++){
 
			points teammember = (points) Teammember.get(i);
 
		}
 
		return Teammember.Deductions;
	}
