java我试图创建一系列Employee对象，这些对象的数量与其从文件中读取的行数相同

Question

行列表 私有数组列表行

list of Employee objects
private ArrayList<Employee> employeeList;

the file information of employee
private FileReader file;

public HumanResource(String fileName)
{
    file = new FileReader(fileName);
    ArrayList<Employee> employeeList = new ArrayList<>();
    for (int k = 0; k < file.getLines().size(); k++)
    {
       employeeList.add(new Employee (file.getLines().get(k)));
       
    }
}

这是我到目前为止提出的，但idk是否正确

Answer 1

更好的方法是使用BufferReader，你可以阅读每一行

try(BufferedReader br = new BufferedReader(new FileReader(fileName))){
  
  string st;
  ArrayList<Employee> employeeList = new ArrayList<>();
  while ((st = br.readLine()) != null)
    employeeList.add(new Employee(st));
  }
}

请注意，我正在使用try{}扭曲bufferedReader，以便它自动关闭
