Trying to read a file but doesnt know how to get the size of the inputstrem

Question

hi im trying to read a file in a cel this is my code:
fconn = (FileConnection)Connector.open("file://localhost/" + actualdir);                     
InputStream fis = fconn.openInputStream();                                                 
byte b[] = new byte[1024];                                                                         
fis.read(b);                         
fis.close();
fconn.close();   
textBox1 = new TextBox("Viendo el Archivo: " + list1.getString(list1.getSelectedIndex()), null, 1024,TextField.ANY | TextField.UNEDITABLE);                       
                          textBox1.setString(new String(b, 0, b.length));                        i dont want to create always an array of bytes of size 1024 instead i wanna know how many bytes does inputstream object has, how can i know that?

Answer 1

you can either retrieve the whole file at once by determine the file size like:
fconn = (FileConnection)Connector.open("file://localhost/" + actualdir);
InputStream fis = fconn.openInputStream();
byte b[] = new byte[fconn.fileSize()];
fis.read(b);
fis.close();
fconn.close();
or read every single byte
fconn = (FileConnection)Connector.open("file://localhost/" + actualdir);
InputStream fis = fconn.openInputStream();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int i = fis.read();
while(i != -1){
baos.write(i);
fis.read();
String content = new String(baos.toByteArray());
