What is the best way to check which index is executing in a loop without too much slow down the process?
For example I want to find all long fancy numbers and have a loop like
for( long i = 1; i > 0; i++){
//block
}
and I want to learn which i is executing in real time.
Several ways I know to do in the block are printing i every time, or checking if(i % 10000), or adding a listener.
Which one of these ways is the fastest. Or what do you do in similar cases? Is there any way to access the value of the i manually?
