我已經弄清楚如何將文本文件中的內容讀取、存儲和顯示到數組中，但我的問題是當用戶按下數字時僅輸出特定行..例如，如果用戶輸入 3，它應該顯示文本文件第三行中的所有內容..這是我迄今為止所擁有的內容的片段。文本文件將包含 john、doe、[email protected]、10101、blue、342.21 等內容。謝謝！public static void readLine(Record[] objects) throws FileNotFoundException {    Scanner in = new Scanner(System.in);    File fileobject = new File(filename);    Scanner input = new Scanner(fileobject);        String[] array;        System.out.println("Enter the record you would like to see: ");        int userChoice = in.nextInt();        for (int i = 0; i < userChoice; i++) {                objects[i] = new Record();                array = input.nextLine().replaceAll(" ", "").split(",");                objects[i].firstname = array[0];                String name = array[0];                objects[i].lastname = array[1];                String lastname = array[1];                objects[i].email = array[2];                String email = array[2];                objects[i].idnumber = Double.parseDouble(array[3]);                double idnumber = Double.parseDouble(array[3]);                objects[i].color = array[4];                String color = array[4];                objects[i].balance = Double.parseDouble(array[5]);                double balance = Double.parseDouble(array[5]);                passThis(name, lastname, email, idnumber, color, balance, userChoice);        }          }    public static void passThis(String firstname, String lastname, String email, double idnumber, String color, double balance, int userChoice) {           System.out.println(firstname + " " + " " + lastname + " " + email + " " + (int)idnumber + " " + color + " " + balance);    }
