Well, the code will "work", in that temp will have the right value
after the call. However, this is almost a matter of luck, as the code
is very poorly written -- here's a cleaned up version:
...
String temp = process_me();
out.println(temp);
...
public String process_me()
{
return "my name";
}
There's no reason to initialize temp to null, and no reason for
process_me to have a parameter.
It's also not quite clear what the original poster wants. I echo the
suggestion that he read up on more basic Java stuff, and then some
servlet stuff, instead of posting such questions to this list.
