hi my name is exodiamaster3.14 my code runs but when it runs it tells me
System.out.println(" Hello Duelist, my name is Yusie Fudo.This is the one and only Specific Rare Yu-Gi-Oh! card vending.Each card in this vending machine is sealed in a special card container.These cards are up to date with the currnet ban list and pack release's.");
          System.out.println(" in order to get cards, you will be asked to pay using your Deck Points, which are stored on your Acadmey Duel Disc");
          System.out.println("Please insert Deck Points equal to the card(s) you would like to purchase or just insert 1,703.87 Deck points");
