Declaring outside a loop: speed? memory?

Hello
Just wondering, is there a speed or memory difference between the two following codes? What is recommended? Which will easier garbage collect (suppose MyClass is big)?

--- code ---
for(int i = 0; i < 1000; i++){
MyClass mine = new MyClass();
mine.doSomething();
}
------------
and
--- code ---
MyClass mine;
for(int i = 0; i < 1000; i++){
mine = new MyClass();
mine.doSomething();
}
------------

Thanks for your answers
Phil
