Question

我正在寻求帮助。我有一个应用程序在工作中生成一个带有用户信息的csv。我想使用Java并获取数据，删除重复信息，重新排列信息并创建电子表格，以使生活更轻松。 csv按以下格式生成，但要大得多：

21458952, a1234, Doe, John, technology, support staff, work phone, 555-555-5555

21458952, a1234, Doe, John, technology, support staff, work email, johndoe@whatever.net

21458952, a1234, Doe, John, technology, support staff, work pager, 555-555-5555

99946133, b9854, Paul, Jane, technology, administration, work phone, 444-444-4444

99946133, b9854, Paul, Jane, technology, administration, work email, janepaul@whatever.net

99946133, b9854, Paul, Jane, technology, administration, work pager, 444-444-4444

99946133, b9854, Paul, Jane, technology, administration, cell phone, 444-444-4444

我想删除重复项并将数据排列在适当的列中。

ID | PIN | Lname | Fname | Dept | team | work px | work email

我一直在尝试使用BufferedReader构建数组来存储数据，但是我遇到了处理重复数据并将数据操作到表中的困难。

这是我到目前为止的代码

public class Sort {

   public static void main(String[] args) {

     BufferedReader br = null;

     try{
            String line="";
            String csvSplitBy=(",");
            String outPut;

            br = new BufferedReader(new FileReader("C:/Users/Jason/Desktop/test.txt"));    //location where the file is retreived 

            while ((line = br.readLine()) !=null){  //checks to see if the data is there
                   String[] id = line.split(csvSplitBy);

                   outPut = id[0] + "," + id[1] + "," + id[2] + "," + id[3] + "," + id[4] + "," + id[5] + "," + id[6] + "," + id[7]
                           + "," + id[8] + "," + id[9];//incomplete...using for test...


                 System.out.println(outPut);   //displays the contents of the .txt file
                   } //ends while statement 
             } //ends try

     catch (IOException e){
            System.out.println ("File not found!");
         } //ends catch
         finally{
                try{
                       if (br !=null)br.close();}
                catch(IOException ex){
                       ex.printStackTrace();
                } //ends try
         } //ends finally
   } //ends main method

} //结束课程排序

感谢您的帮助！

你应该创建一个类来保存数据，然后创建一个List，然后如果数据不在列表中，添加它！

从csv中删除重复项并使用JAVA将数据重新排列为列
