The following is the use of scanner in jdk1.5
/**//*
Scanner Scanner = new Scanner (instream);
PrintWriter out = new PrintWriter (OutStream);

Out.write ("Welcome to the Echo server of MIDI");
Out.write ("Exit service Please enter BYE");
Out.flush ();
Boolean done = false;

while (!done && scanner.hasnextline ()) {
String line = Scanner.nextline ();
Out.write ("Echo:" +line+ ");
Out.write ("Please enter the command ...)." ");
Out.flush ();
if (Line.trim (). Equals ("BYE"))
Done=true;
}
