java 实现读取txt文本数据并以数组形式一行一行取值

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
 
public class ReadFiledata {
 public static String txt2String(File file){
  StringBuilder result = new StringBuilder();
  try{
   BufferedReader br = new BufferedReader(new FileReader(file));//构造一个BufferedReader类来读取文件
   String s = null;
   while((s = br.readLine())!=null){//使用readLine方法，一次读一行
    result.append(System.lineSeparator()+s);
   }
   br.close(); 
  }catch(Exception e){
   e.printStackTrace();
  }
  return result.toString();
 }
 
 public static void main(String[] args){
  File file = new File("F:/card.txt");//我的txt文本存放目录，根据自己的路径修改即可
  System.out.println(txt2String(file));
 }
}

try{
 String s = "";
   BufferedReader in =new BufferedReader(new FileReader("F:\\tel.txt"));
   while((s=in.readLine())!=null){
   String[] split = s.split(",");
   String tel = split[0];
   driver.findElement(By.xpath("//input[@id='register-phone']")).sendKeys(tel);//输入正确手机号
   driver.findElement(By.xpath("//input[@id='register-imgcode']")).sendKeys("1234");//输入图片验证码
   driver.findElement(By.xpath("//input[@id='register-msgcode']")).sendKeys("123456");//输入短信验证码
   driver.findElement(By.xpath("//input[@id='register-password']")).sendKeys("Abc123");//输入正确密码
   driver.findElement(By.xpath("//input[@id='register-confirmpassword']")).sendKeys("Abc123");//再次输入确认密码
   driver.findElement(By.xpath("//input[@id='agree']")).click();//勾选同意协议按钮
 } 
 }catch(FileNotFoundException e){
 e.printStackTrace();
   }
 catch(IOException e){
   e.printStackTrace();
   }
