Does this code effect performance.

Question

I am doing some code now :) and I did a method like this, however I do not know if it effects performance for the whole application when the method is being called, or weather it is a good coding standard.
The code in question is the following:
public void myMethid(){
   class c{
      public c(String s){
          System.out.println(s);
   c myC = new c("Hello");
}I know this is a stupid example, however would such a think effect performance, or be wrong? ... would it be better to just declare c as an external class?
regards,

Answer 1

I have seen ppl complaining about cross posts, but what I am going to do here is cross post my answer, which I feel might be helpful in this situation, and considering that it still lies in the grey area:-
"I smell a very interesting discussion stemming out of it, but your question is as open ended as it could be, what kind of web application and what performance. performance is the most misused word I have come across in a lot of design considerations. It is not one parameter you could measure but a combination of different considerations, which would be as follows:-
1) Response time
2) Responsivesness
3) Latency
4) Thoroughput
5) Load
6) Load sensitivity
7) Efficiency
8) capacity
9) scalabilty
You might want to look on the web as to what they mean since I am not going to go into that detail. But these attributes are independent of each other, an application with good latency might be poor in scalability or other way around, so it depends as to whats the nature and requirements of the app you are looking at then deciding which way you would want to go. Its not that simple.
Secondly I would quote Martin Fowler from his book "Patterns of Enterprise Application Architecture":-
"Too often I have seen designs used or rejected because of performance considerations, which turn out to be bogus once somebody actually does some measurements on the real setup used for the application."
So please go back to the requirements and try to figure out what you are actually looking for."
