下面的法典是我目前掌握的,但当时它超越了卷宗中的任何数据,而不是把数据放在最后。 这样做是否容易?

public void printCustomerList() throws IOException{
        FileWriter pw = new FileWriter("F:\data.csv");
        Iterator s = customerIterator();
        if (s.hasNext()==false){
            System.out.println("Empty");
        }
        while(s.hasNext()){
            Customer current  = (Customer) s.next();
            System.out.println(current.toString()+"
");
            pw.append(current.getName());
            pw.append(",");
            pw.append(current.getAddress());
            pw.append("
");
        }
            pw.flush();
            pw.close();
    }
