在Java中读取文本文件时如何访问行的值

Question

I am trying to load in two files at the same time but also access the first gps1 file. I want to access the gps1 file line-by-line and depending on the sentence type which I will explain later I want to do different stuff with that line and then move to the next line.

Basically gps1 for example has multiple lines but each line falls under a couple of catagories all starting with $GPS(then other characters). Some of these types have a time stamp which I need to collect and some types do not have a time stamp.

                    File gps1File = new File(gpsFile1);
        File gps2File = new File(gpsFile2);

        FileReader filegps1 = new FileReader(gpsFile1);
        FileReader filegps2 = new FileReader(gpsFile2);

        BufferedReader buffer1 = new BufferedReader(filegps1);
        BufferedReader buffer2 = new BufferedReader(filegps2);


        String gps1;
        String gps2;

        while ((gps1 = buffer1.readLine()) != null) {

The gps1 data file is as follows

$GPGSA,A,3,28,09,26,15,08,05,21,24,07,,,,1.6,1.0,1.3*3A
$GPRMC,151018.000,A,5225.9627,N,00401.1624,W,0.11,104.71,210214,,*14
$GPGGA,151019.000,5225.9627,N,00401.1624,W,1,09,1.0,38.9,M,51.1,M,,0000*72
$GPGSA,A,3,28,09,26,15,08,05,21,24,07,,,,1.6,1.0,1.3*3A

Thanks

I don't really understand the problem you are facing but anyway, if you want to get your lines content you can use a StringTokenizer

StringTokenizer st = new StringTokenizer(gps1, ",");

And then access the data one by one

while(st.hasMoreToken) String s = st.nextToken();

EDIT: NB: the first token will be your "$GPXXX" attribute
