Gah. I'm trying to call a method from one class to another. The TA's
are overloaded so I got no one, can anyone tell me what's wrong? I've
had one java class like a year ago. Kinda rusty. Thanks!

class NumArrayList implements NumList
{
  double [] Numbers = new double[3];

  public void main(String args[]){

    Numbers[0] = 100000;
    Numbers[1] = 20.9;
    Numbers[2] = 3;
  }
  public void printArray(){
  for(int i = 0; i<Numbers.length;i++)
    System.out.print(Numbers[i] + " ");
  }
}

public interface NumList {
  printArray();
}

Something like this? The method main() must be static. Initialize your
instance variable, typically a lower case name, in the NumArrayList
constructor. For variety, I've implemented NumList using a for-each
loop.

public class Main {

    public static void main(String[] args) {
        new NumArrayList().printArray();
    }
}

interface NumList {
    void printArray();
}

class NumArrayList implements NumList {

    double[] numbers = new double[3];

    public NumArrayList() {
        numbers[0] = 100000;
        numbers[1] = 20.9;
        numbers[2] = 3;
    }

    @Override
    public void printArray() {
        for (double d : numbers) {
            System.out.print(d + " ");
        }
    }
}
