Hi.
I used this example from sdk. But why it show me wrong text instead of hello world after I use read function. Here is that function:
System.out.println(inBuf);
System.out.println(outBuf);


Here is source code:

int MIN_SPACE = 100;
String fileName = "testfile";
String newName = "testfile1";
byte[] outBuf = "Hello, World!".getBytes();
byte[] inBuf = new byte[15];

/* Check if there is enough space available */
if (File.spaceAvailable() < MIN_SPACE)
throw new IOException("Not enough MMC space");
/* Create and open new file */
File file = new File();
int fileDesc = file.open(fileName);
if ( fileDesc < 0)
throw new IOException("Failed to open file");
/* Write "Hello, world!" string to the file */
if ( file.write( fileDesc, outBuf, 0, outBuf.length ) != outBuf.length )
throw new IOException("Error in writing file");
/* Check the file lenght */
//if (file.length(fileDesc) != outBuf.length)
//throw new IOException("Erroneous file");
/* Read "World" using seek() and read() methods */
if (file.seek(fileDesc, 0) != 0)
throw new IOException("Error in seek() for file");
if (file.read(fileDesc, inBuf, 0, 10) != 10)
throw new IOException("Error in reading file");
System.out.println(inBuf);
System.out.println(outBuf);
/* Close file */
if (file.close(fileDesc) < 0)
throw new IOException("Failed to close file");
/* Now use methods that don't require file opening */
/* Rename */
if (File.rename(fileName, newName) < 0)
throw new IOException("Failed to rename file");
/* Check existence */
if (File.exists(newName) < 0)
throw new IOException("File does not exists");
/* Copy back */
if (File.copy(newName, fileName) < 0)
throw new IOException("Failed to copy file");
/* Append string using debugWrite() */
if (File.debugWrite(fileName, "Debug string") <= 0)
throw new IOException("Failed to write debug string");



please help me.
