Andre/Len
in case the earlier responses did not answer how to receive a CharSet encoded
InputStream to a reader
suggest implmenting a Reader which will accomodate charset (such as
InputStreamReader)
http://java.sun.com/j2se/1.5.0/docs/api/java/io/InputStreamReader.html
InputStreamReader
public InputStreamReader(InputStream in,
Charset cs)
Create an InputStreamReader that uses the given charset.
Parameters:in - An InputStreamcs - A charsetSince:1.4
BTW: Int to Char conversion
String new_string=new java.lang.Integer(int int_input).toString();
BTW: CharToInt conversion
int inta=new java.lang.Integer(String str_input).intValue();
