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 + " ");
}
}
}

That makes so much more sense. Thank you. That gets me in the right
