Long File opening time

[Vitalik100]

Hello, I wrote simple program that reading *.jpg file into byte array.
But when i trying to open 400 kB jpg file it takes about 2 minutes.
I am using NOKIA 6233. Is it normal time for opening such size files?
But when you browsing jpg photos by internal tools it takes time not more than 2 second.
How can i reduce opening time, is there any othere means in J2ME?
Will be this time smaller if i will using C++ progrmming?
My code:
String s1;

s1 = System.getProperty("fileconn.dir.memorycard")+"proba.jpg";
FileConnection fc = (FileConnection)Connector.open(s1,Connector.READ);

DataInputStream txtinStream = fc.openDataInputStream();

ByteArrayOutputStream bStrm = new ByteArrayOutputStream();
int ch;
while ((ch = txtinStream.read()) != -1) bStrm.write(ch);
DataArray = bStrm.toByteArray();

stringItem2.setText(s1 + " "+java.lang.String.valueOf(DataArray.length));

fc.close();

You should not read file byte by byte, I guess that's why it takes so long to load it.
Try to read file in buffer with read(char[] cbuf, int off, int len) method.

That's right. You might find this document helpful.

For better performance u have to read data in chunks. Instead of reading data byte by byte, read it in chunks.
use inputsream.read(byte[],offset,length) for better performance..

check and revert..
