java - 如何将用户的输入保存到单独的文本文件中

Question

首先，我必须道歉，因为有很多这样的问题，但我不太明白。我正在学习 Java 教程，但我被困在这里了。

如何将用户的输入存储到文本文件中？

这是我的代码。

import java.util.ArrayList;
import java.util.Scanner;
import java.util.Random;

public class UserInput {

public static void main(String[] args) {

    ArrayList<String> fullName = new ArrayList<String>();
    ArrayList<String> userId = new ArrayList<String>();
    ArrayList<String> qA = new ArrayList<String>();

    Scanner sc = new Scanner(System.in); 

    while (true) {

       System.out.println("Please enter your Full Name: ");
       fullName.add(sc.nextLine());

       System.out.println("Please enter your ID: ");
       userId.add(sc.nextLine());

       System.out.println("What is your race/ethinicity? A. Hispanic/Latino, B. Asian, C. Caucasian, D. African American: ");
       qA.add(sc.nextLine());

       System.out.println("What is your preferred language? A. Spanish, B. English, C. Portugues, D. French: ");
       qA.add(sc.nextLine());

       System.out.println("What is your political affiliation? A. Republican, B. Democrat, C. Green, D. None: ");
       qA.add(sc.nextLine());

       System.out.println("What is your religious practice? A. Christian, B. Islam, C. Judaism, D. Hinduism: ");
       qA.add(sc.nextLine());

       System.out.println("What is your sexual orientation? A. Homosexual, B. Heterosexual, C. Bisexual, D. Asexual: ");
       qA.add(sc.nextLine());

       System.out.println("What is your favorite ice cream? A. Vanilla, B. Chocolate, C. Banana, D. Gum: ");
       qA.add(sc.nextLine());

       System.out.println("What is your favorite activity? A. Running, B. Walking, C. Sleeping, D. Eating: ");
       qA.add(sc.nextLine());

       System.out.println("What is your favorite color? A. Burgundy, B. Black, C. Gold, D. Blue: ");
       qA.add(sc.nextLine());

       System.out.println("What is your favorite clothing item? A. Shoes, B. Hats, C. Shirts, D. Rings: ");
       qA.add(sc.nextLine());

       System.out.println("What is your favorite pet? A. Dog, B. Cat, C. Tiger, D. Turtle: ");
       qA.add(sc.nextLine());

       Random random = new Random();

       for (int i =0; i < 1; i++) {

           int answerScore = random.nextInt(10) + 1;
           System.out.println("Test Score " + answerScore + "/10");

       }

       break;

    }
}

}

我想知道如何将用户的姓名、ID 和答案存储到单独的 .txt 文件中。

提前致谢!

 public void saveData(ArrayList<String>fullName){ 
     try {
        File newTextFile = new File("D:/textfile.txt");//path of the file 
        FileWriter fw = new FileWriter(newTextFile);
        for(String str: fullName) {
        fw.write(str);
        }
        fw.close();

    } catch (IOException io) {
        io.printStackTrace();
    }
