Reading little endian binary files
Hi,
Recently I tried to read from a little endian binary files. Here is the code:
FileInputStream file_input = new FileInputStream (file);
DataInputStream data_in= new DataInputStream (file_input );
while (true) {
try {
short i_data = data_in.readShort ();
}
catch (EOFException eof) {
System.out.println ("End of File");
break;
}
System.out.println ( i_data );
}
But I am getting wrong values (big-endian). I will be pleased if anyone can help me in this respect.
Given your FileInputStream, get a FileChannel from it. Using the
FileChannel, map the entire file (or part of it) to a ByteBuffer. The
ByteBuffer can have its endianess set by the order method. Read your
shorts from this ByteBuffer. This is all nio stuff; check out the APIs.
kind regards,
Jos
Hi,
Finally, I can do it easily with reading little endian binary files in java. Here is the code:
FileInputStream file_input = new FileInputStream (file);
DataInputStream data_in = new DataInputStream (file_input );
while (true) {
try {
int low = data_in.readByte() & 0xff;
int high = data_in.readByte() & 0xff;
short i_data = (short) (high << 8 | low) ;
}
catch (EOFException eof) {
System.out.println ("End of File");
break;
}
System.out.println ( i_data );
}
