Performance tip: Primitives and Methods

June 10, 2005 burakk

"Use the Object version of primitive values in your application and not the primitives themselves for method intensive variables"

But not always.

"Simple computation like a*b or expressions like a = !b are much slower if you are using objects."

When you use a method of a primitive type, a wrapper object will be created and "the creation of the wrapper-object costs time that you maybe don’t have".
