readLine() method

[cold80]

I'm starting to develop a Java application using sockets and IO
objects. I developed, for example, a sample Echo Server application
that read the input from a socket using a BufferedReader object and
write in the socket the same text using a BufferedWriter. But when I
read a string from BufferedReader using readLine() method, I receive a
string that starts with some strange characters. So I can't write this
string with a simple println(), and I don't know how I can do this. I
think these strange chars are some kind of format that java need to use
these objects, really I don't know...Could you help me please?

Many thanks

Sebastiano

If you merely want to echo input data back across a socket, don't bother
using Reader objects, just use a char[] and Input / Output streams

-----------------------------------^^^^^^

You misspelled "byte[]". Otherwise the advice is sound.

Ok, but I want to understand more about these IO objects. So I would
like to know why the return string of the method readLine() contains
these strange chars and how I can convert this string in a normal
string.

Thank you for you patience

Hmm, most likely the readLine() method tries to encode input into
characters that is not meant to be encoded. "Random" binary data. And the
result will generally be less then well-readable.

Oh, and yes. I meant byte[]. I should know them by now (and hate them).
