java - 如何在给定的搜索中加载相应的数据

Question

我已经编写了一个程序，可以将输入的数据保存在文本字段中。它的保存技巧是这样的

data0 = student number
data1 = name
data2 = section
data3 = cp
data4 = email
data5 = address

在保存的文件中:

data0 | data1 | data2 | data3 | data4 | data5
data0 | data1 | data2 | data3 | data4 | data5
data0 | data1 | data2 | data3 | data4 | data5
data0 | data1 | data2 | data3 | data4 | data5
data0 | data1 | data2 | data3 | data4 | data5

data0 具有唯一性，这是我用来搜索学号“data0”的代码例如，如果我搜索 12293

data0 | data1 | data2 | data3 | data4 | data5
data0 | data1 | data2 | data3 | data4 | data5
12293 | blahh | blehh | blihh | blohh | bluhh
data0 | data1 | data2 | data3 | data4 | data5

第 3 行有一个匹配，blah,blehh,blihh,blohh,bluhh 必须打印在不同的文本区域

但我不知道如何切片 data1|data2|data3|data4|data5|当搜索匹配时放入数组

这是我的代码:

    public static void main(String[] args) throws UnsupportedEncodingException, FileNotFoundException, IOException {
        try{
      FileInputStream fstream = new FileInputStream("data.dat");
            try (DataInputStream in = new DataInputStream(fstream)) {
                BufferedReader br = new BufferedReader(new InputStreamReader(in));
                String strLine;
                while ((strLine = br.readLine()) != null)   {

                 if (strLine.startsWith("JFETZ")){
                 System.out.println("Data Found");

                 }
                 else
                 {System.out.println("Nothing Found in this line");}
                }
            }
      }catch (Exception e){
          System.err.println("Error: " + e.getMessage());
      }
    }
}

split()通过 | 执行

String values[] = strLine.split("\\|");

并将搜索键与数组的第一个元素进行比较values[0]

while ((strLine = br.readLine()) != null)   {
 String values[] = strLine.split("\\|");
 if ("JFETZ".equals(values[0]))){
   System.out.println("Data Found");
 }else{
   System.out.println("Nothing Found in this line");}
 }
}
