Question

I have a for loop and structure like this:

for(....)
....
....
if(isTrue)
... do something..
.. method to be executed once (doTrick) is declared outside for loop.
....endif
endfor

public void doTrick()
...
...
..end

Is it possible for a method in for loop to be executed only once?

Answer 1

Sure!..

if(!alreadyExecuted) {
    doTrick();
    alreadyExecuted = true;
}
