when looping, for instance:
for ( int j = 0; j < 1000; j++) {}; and I need to instantiate 1000 objects, how does it differ when I declare the object inside the loop from declaring it outside the loop ??
for ( int j = 0; j < 1000; j++) {Object obj; obj =}
vs
Object obj;
for ( int j = 0; j < 1000; j++) {obj =}
It's obvious that the object is accessible either only from the loop scope or from the scope that is surrounding it. But I don't understand the performance question, garbage collection etc.
What is the best practice ? Thank you
