Question

So for an assignment I have to read from a input file that is formated as so:
Miller <— last name
William <—first name
00001 <— account ID
891692 06 <— account balance

These four lines represent an “account”. From a main method I have to call from another class called account and run a method in that class called toString()
toString() is supposed to print out those four lines in this format:
00001, Miller, William, $891692.06

Here’s what I have in my main method so far:

 int count = 1;
    while(read.hasNextLine()) {
        String nextLine = read.nextLine();
            account.toString(nextLine);
        if(count %4==0) {
            vector.addAccount(nextLine);
        }
        count++;
    } 

And this is whats in my toString method:

public String toString(String line) {
 for(int i = 0; i < position; i++){
  line = info[i]; 
    position++;
     }
     return System.out.println(info[2]+", "+info[0]+", "+info[1]+", "+info[3]);
}

In toString I’m getting an error with the return statement and also I need to format info[3](which should end up being the account balance) so that it will be in dollar notation when it prints like: $00.00

Any help is much appreciated! Thanks!

Incorporating Nambari’s tip, you should try it as the following code:

int count = 1;
while(read.hasNextLine()) {
    String nextLine = read.nextLine();
        System.out.println(account.toString(nextLine));
    if(count %4==0) {
        vector.addAccount(nextLine);
    }
    count++;
} 

And the toString method:

public String toString(String line) {
   for(int i = 0; i < position; i++){
      line = info[i]; 
      position++;
   }
   return info[2]+", "+info[0]+", "+info[1]+", "+info[3];
}
