Passing array to another class?

Question

I have this code which reads in a text file and stores the data in the race array.
import java.io.*;
import java.util.*;
public class Runner {
    public static void main(String[] args) throws IOException {
        BufferedReader in = new BufferedReader(new FileReader("race1.txt"));
        String line;
        while ((line = in.readLine()) != null) {
            String[] race = line.split(",");
            int position = Integer.parseInt(race[0]);
            String name = race[1];
            String team = race[2];
            System.out.println("position=" + position + ", name=" + name + ", team=" + team);
               in.close();
   }What I want to do is use the race array in another class called Results to perform some calculation methods with the results. So far I haven't been able to get anything to work. Anyone got any advice?

Answer 1

I was mistaken. Your array isn't of type Race[] or Runner[], but of String[]. Change the declaration accordingly.
It's not difficult to understand. At one point, you declare a method and define the parameters (in this case a String[]). Once you do that, you have to make sure that you actually do pass a String[] if the method needs one.
There's no difference in handling parameters, regardless if it's an object, an array, or a primitive value.
