Declare an object inside or outside a loop?

Question

Is there any performance penalty for the following code snippet?

for (int i=0; i         


        

Answer 1

These have different semantics. Which is more meaningful?

Reusing an object for "performance reasons" is often wrong.

The question is what does the object "mean"? WHy are you creating it? What does it represent? Objects must parallel real-world things. Things are created, undergo state changes, and report their states for reasons.

What are those reasons? How does your object model and reflect those reasons?
