读取多行文本，其值之间用空格隔开 [英] Read multiline text with values separated by whitespaces

问题描述

我有以下测试文件:

Jon Smith 1980-01-01
Matt Walker 1990-05-12

解析此文件每一行并创建带有(名称，姓氏，生日)的对象的最佳方法是什么?当然，这只是一个示例，实际文件中有很多记录.

What is the best way to parse through each line of this file, creating object with (name, surname, birthdate) ? Of course this is just a sample, the real file has many records.

推荐答案

 import java.io.*;
 class Record
{
   String first;
   String last;
   String date;

  public Record(String first, String last, String date){
       this.first = first;
       this.last = last;
       this.date = date;
  }

  public static void main(String args[]){
   try{
    FileInputStream fstream = new FileInputStream("textfile.txt");
          DataInputStream in = new DataInputStream(fstream);
          BufferedReader br = new BufferedReader(new InputStreamReader(in));
          String strLine;
          while ((strLine = br.readLine()) != null)   {
   String[] tokens = str.split(" ");
   Record record = new Record(tokens[0],tokens[1],tokens[2]);//process record , etc

   }
   in.close();
   }catch (Exception e){
     System.err.println("Error: " + e.getMessage());
   }
 }
}
