如何制作对象的动态列表

假设我有一个CSV文件为：

employees.csv
ID,Name,Role,Salary
1,Pankaj Kumar,CEO,"5,000USD"
2,Lisa,Manager,500USD
3,David,,1000USD

我可以将其解析为Employee对象列表：

Employee.java
package com.journaldev.parser.csv;
public class Employee {
    private String id;
    private String name;
    private String role;
    private String salary;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getRole() {
        return role;
    }
    public void setRole(String role) {
        this.role = role;
    }
    public String getSalary() {
        return salary;
    }
    public void setSalary(String salary) {
        this.salary = salary;
    }
    @Override
    public String toString(){
        return "ID="+id+",Name="+name+",Role="+role+",Salary="+salary+"n";
    }
}

但是，如果我想制作我的代码，这样它就可以处理或多或少有列的文件，而不需要事先知道它们的名称：

employees.csv
ID,Name,Role,Salary, dateJoined, sex
1,Pankaj Kumar,CEO,"5,000USD",Jan 05 2014 12:04:01PM,MALE
2,Lisa,Manager,500USD,Feb 11 2012 12:04:01PM, FEMALE
3,David,,1000USD,Jan 02 2013 12:04:01PM, MALE

我想这样做，这样文件中的列数就无关紧要了。因此，对于文件中的每一列，代码都会在对象列表中创建另一个元素。

我的代码的其余部分：

package openCSV_fileReader;
import java.io.FileReader;
import java.io.IOException;
import java.io.StringWriter;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import au.com.bytecode.opencsv.CSVReader;
import au.com.bytecode.opencsv.CSVWriter;
public class OpenCSV_fileReader {
     public static void main(String[] args) throws IOException {
            List<Employee> emps = parseCSVFileAsList();
            System.out.println("**********");
            writeCSVData(emps);
     }
        private static void writeCSVData(List<Employee> emps) throws IOException {
            StringWriter writer = new StringWriter();
            CSVWriter csvWriter = new CSVWriter(writer,'#');
            List<String[]> data  = toStringArray(emps);
            csvWriter.writeAll(data);
            csvWriter.close();
            System.out.println(writer);
        }
        private static List<String[]> toStringArray(List<Employee> emps) {
            List<String[]> records = new ArrayList<String[]>();
            //add header record
            records.add(new String[]{"ID","Name","Role","Salary"});
            Iterator<Employee> it = emps.iterator();
            while(it.hasNext()){
                Employee emp = it.next();
                records.add(new String[]{emp.getId(),emp.getName(),emp.getRole(),emp.getSalary()});
            }
            return records;
        }
        private static List<Employee> parseCSVFileAsList() throws IOException {
            CSVReader reader = new CSVReader(new FileReader("employees.csv"), ',');
            List<Employee> emps = new ArrayList<Employee>();
            //read all lines at once
            List<String[]> records = reader.readAll();
            Iterator<String[]> iterator = records.iterator();
            //skip header row
            iterator.next();
            while(iterator.hasNext()){
                String[] record = iterator.next();
                Employee emp = new Employee();
                emp.setId(record[0]);
                emp.setName(record[1]);
                emp.setRole(record[2]);
                emp.setSalary(record[3]);
                emps.add(emp);
            }
            reader.close();
            System.out.println(emps);
            return emps;
        }     
}

这可行吗？这就是我很难找到这样做的方法的地方。
