Can you pass elements in a string arraylist to a function?

Question

I made a function that is reading a file and putting each line in an array of size 8 which is then adding that array to an arraylist. I am then taking each value per line and trying to pass them into functions but for some reason I am getting null pointers exceptions. Is it because I am using an arraylist? The functions themselves are working if I pass the parameters through the console. I am trying to take the Strings and pass them to a function. example: dep(eachLine.get(0)[1]) does not work. I even created get functions for each slot and put them in a loop with a nested loop to try and pull out the values and it's not working.

public void readFile(String x) throws IOException{
    File file = new File(x);
    BufferedReader br = new BufferedReader(new FileReader(file));
    String str="";

    while((str = br.readLine())!= null)
    {
        String line[] = new String[8];
        int count =0;
        StringTokenizer token = new StringTokenizer(str,",");
        while(token.hasMoreTokens())
        {
            line[count]= token.nextToken();
            count++;
        }

        eachLine.add(line);
    }
}

public int getAccountInt(int i){
    //readFile(x);
    return Integer.parseInt(eachLine.get(i)[4]);
}
public String getName(int i){
    //readFile(x);
    return eachLine.get(i)[1];
}
public int getSSNUM(int i){
    //readFile(x);
    return Integer.parseInt(eachLine.get(i)[2]);
}
public String getAddress(int i){
    //readFile(x);
    return eachLine.get(i)[3];
}
public int getCCAccountInt(int i){
    //readFile(x);
    return Integer.parseInt(eachLine.get(i)[6]);
}
public double getDepositInt(int i){
    //readFile(x);
    return Double.parseDouble(eachLine.get(i)[5]);
}
public double getCreditInt(int i){
    //readFile(x);
    return Double.parseDouble(eachLine.get(i)[7]);
}
public String getCommand(int i){
    //readFile(x);
    return eachLine.get(i)[0];
}

this is in main

x.readFile("today.txt"); System.out.println(x.eachLine.get(0)[4]);

for(int i =0;i<x.eachLine.size();i++){


        String f = x.getCommand(i);
        String s = x.getName(i);
        int a = x.getSSNUM(i);
        String t = x.getAddress(i);
        int b = x.getAccountInt(i);
        double d = x.getDepositInt(i);
        int c = x.getCCAccountInt(i);
        double e = x.getCreditInt(i);

        if(f.equals("ONA")){

        db.createAll(s, a, t, b, d, c, e);


    }
