Help on process(str) ?

[SDragonX]

I'm new with JAVA so could anyone help me with this:

try {
BufferedReader in = new BufferedReader(new FileReader("infilename"));
String str;
while ((str = in.readLine()) != null) {
process(str)
}
in.close();
} catch (IOException e) {
}

, Now, I don't know what is ment by process.

Could anyone point me in the right direction here.

Thanks in Advance
