Method 1 or Method 2

Question

Hi,
Does somebody know the best way to read something from the system.in?
Method 1
=======
InputStreamReader r = new InputStreamReader( System.in );
int maxch = Integer.parseInt(System.getProperty("cgi.CONTENT_LENGTH"));
char [] bf = new char[maxch];
try{
r.read(bf);
}catch(Exception ex){}
String inpbuffer = new String(bf);
Method 2
=======
InputStreamReader r = new InputStreamReader( System.in );
int maxch = Integer.parseInt(System.getProperty("cgi.CONTENT_LENGTH"));
char [] bf = new char[maxch];
int nred = 0;
while (nred < maxch)
try{
nred += r.read(bf,nred,maxch-nred);
}catch (Exception ex){}
String inpbuffer = new String(bf);
Thx in advance
Pieter

Answer 1

Only the second method reads "maxch" bytes from the stream, the first may stop ahead of time.
It looks like you want to read strings, maybe BufferedReader would be a better tool for your task.
