Hello, I would like to creat a UDP server call Raiza.
 
And I try it to do it my self but it doesn't work on Java Raiza.
 
Could you please help me ?
 
This is my Raiza Code :
 
public class RaizaFileCopier
{
 public static final int BUFF_LEN = 1024;
 
 public static void transfer(InputStream is, OutputStream os) throws IOException
 {
  byte[] data = new byte[BUFF_LEN];
  for (int i = is.read(data); i >= 0; i = is.read(data))
   os.write(data, 0, i);
 }
 
 public static void copyFile(String source, String destination) throws IOException
 {
  try (
   InputStream is =  
    new BufferedInputStream(new FileInputStream(source));
   OutputStream os =  
    new BufferedOutputStream(new FileOutputStream(destination)) )
  {
   transfer(is, os);
  }
 }
 
 public static void main(String[] args) throws IOException
 {
  if (args.length < 2)  
  {
   System.err.println("Usage: java FileCopier source destination" );
   System.exit(-1);
  }
  copyFile(args[0], args[1]);
 }
}
 

wait for while, i answer you after

Les balises code ça vous parle ?

sorry i understand only english
