OutputStreamWriter out = new OutputStreamWriter(output);
copy(input, out);
out.flush();
intcopy(Reader input, Writer output)
Copy chars from a Reader to a Writer. 
char[] buffer = new char[DEFAULT_BUFFER_SIZE];
int count = 0;
int n = 0;
while (-1 != (n = input.read(buffer))) {
    output.write(buffer, 0, n);
    count += n;
return count;
...
StringreadContents(Reader in)
Returns the full contents of the Reader as a String. 
Writer out = null;
try {
    out = new StringWriter();
    copyContents(in, out);
    return out.toString();
} finally {
    try {
        out.close();
...
