why bufferedreader behaves like this?

[Gaurav Chikara]

If i use BufferedReader created by using FileReader object as the parameter to its constructor
like FileReader fr = new FileReader("a.txt");
BufferedReader br = new BufferedReader(fr);
and now i read contents like this way
StringBuffer sb = new StringBuffer();

while(br.read()!=-1)
{
sb.append(br.readLine());
}
Now suppose my contents
of a.txt are like this way
hello world
I m fine
how are you
then contents of stringbuffer made come out to be
ello world
I m fine
ow are you
That means it skips characters at position 1
then how can i retrieve the full contents of a.txt in my stringbuffer

hi,
your br.read reads the first byte of each line

String line;
while ( (line = br.readLine()) != null)
{
   sb.append(line);
}

it's not tested but it should work.

Hi All

Hi
U can try this way it works.
Explanation: I think whenever u read a byte is read & one position is skipped after that u r making a call to readLine().{i'm not sure with this}
Also ,U can use this way or U can just check for null using readLine() in while loop
import java.io.*;
class AAA1
{
public static void main(String args[])throws Exception
{
FileReader fr = new FileReader("a.txt");
BufferedReader br = new BufferedReader(fr);
StringBuffer sb = new StringBuffer();
int c;
while((c = br.read()) !=-1)
{
// code changed here
sb.append((char)c);//br.readLine());
}
System.out.println(sb);
}
}
