Java Cachier - use local variable outside of the loop(or nest it?)

Hi guys! I working on the program that simulates a cashier terminal. I need to use FOR loop to ask user three times about quantity of each of 3 items. Program is ready, but I have a problem with printing GRAND TOTAL because I can't figure out how to use a sub_totals from loops outside of the loop. Yes, I'm noobie) Please help) https://code.sololearn.com/ckhExauxFaBS

Ok. The problem actually was in name of local variables, not in their position, because I already used them outside of the loop. Here is the good code https://code.sololearn.com/cLOL3QOAFhN9 If anybody knows how to make one loop from this 3, I would really appreciate your contribution
