Please help using substring()

Question

char[] data = new char[80];
            int len = 0;
            while ((len = br.read(data, 0, data.length)) != -1 ) {
                //You do now have len characters available in the data.
                 line = new String(data, 0, data.length) + ",";
                 String firstName = line.substring(0,10) + ",";
                 String lasttName = line.substring(10,27) + ",";
                 String startDate = line.substring(27,35) + ",";
                 String address1 = line.substring(35,45) + ",";
                 String address2 = line.substring(45,55) + ",";
                 String city = line.substring(55,65) + ",";
                 String state = line.substring(65,67) + ",";
                 String country = line.substring(67,70) + ",";
                 String zip = line.substring(70,80);
                 String record = firstName+lasttName+startDate+address1+address2+city
                                          +state+country+zip;
            } I'm reading is a file with the code above, and then breaking the lines up into substrings manu with different sized fields. Using this sample input file:
Bob Smith 12 North Rd Denver CO USA 12435
Tom Jones 82 State St Miami FL USA 95764
It reads in the first line fine (Bob, Smith, 12 North Rd, Denver, CO, USA, 12345), but the second line doesn't formatting like it should (ex: Jo,nes 82, State St Mi,ami ...etc)
My guess is that maybe the last element may be causing the problem as in its reading the zip and reading out to 10 chars, but the zip is only 5, and I believe it mayb be overlapping and starting to read the next line somehow.
Any help would be GREATLY appreciated.

Answer 1

From the API documentation:
Returns:
The number of characters read, or -1 if the end of
the stream has been reached. I'm assuming this is regarding the read(byte[]) method of BufferedInputStream?
So how does it know it's reached the end of the
stream(-1) if the actual end of the stream is beyond
80 characters?If there is nothing to read when you call read() then it will return -1. If there is anything to be read, it will return the number of characters read.
I'm asking because I don't know the answer, which I
believe is the solution.No, this has nothing to do with the solution to your problem. The problem is that you're reading to much at a time, you should only read one line at a time.
