difference between accessing class constructor and method in the class

[narasimharao konjeti]

hi every one.
I have one query in terms of performance.

calling the class constructor is expensive and calling the method in the class is expensinsive in terms of performance.

which one is better to pass the parameter.

i.e overloaded class constructor or class method.

waiting for reply.

regards

For an object, you may only call the constructor once, and make your design-decision on this fact.

To compare performance, make a prototyp and test.

[William Brogden]

Generally speaking, it is memory allocation that takes up the most time in object construction.
Of all the reasons to decide between a no-args constructor and one with arguments, performance is so far down the list that it is invisible.
Your architecture should strive for maximum clarity and maintainability and not chase after supposed microscopic performance improvements.
