Thread: Problem with Reading very long line using bufferedReader

I am reading file line by line using bufferedReader in java.
My file contains very long lines (about 913434 characters per line).

FileInputStream inStream=new FileInputStream(inFile);
DataInputStream inDataStream=new DataInputStream(inStream);
BufferedReader br=new BufferedReader(new InputStreamReader(inDataStream));

String str=null;
while ((str = br.readLine()) !=null){
System.out.println(str);
}

But it's always give some portion of line . It's failed to read whole line.
Please , help me on How to read whole line ?

Thanks,

It's failed to read whole line.

How much of the line does it read?
Does it read the same amount every time?

This test program seems to write and read 913434 bytes with no problem.

    String inFile = "LargeFile.txt";   // the file name 
    FileOutputStream fos = new FileOutputStream(inFile);
    for(int i=0; i < 913434; i++) {
      fos.write('A');   // Write all 'A's to the file
    }
    fos.close();
    FileInputStream inStream = new FileInputStream(inFile);
    DataInputStream inDataStream = new DataInputStream(inStream);
    BufferedReader br = new BufferedReader(new InputStreamReader(inDataStream));
 
    String str = null;
    while ((str = br.readLine()) != null){
      System.out.println("len=" + str.length());  // len=913434
    }

How do you know that there is no lineend in the file?
What bytes are in the file at the location where readLine() stops reading a line?

Thanks for your suggestions
