Need help

I have to make the game "War" for my computer science class. We were instructed to use arrays to accomplish this. Once a card from one deck is used, how would I add it to the other persons deck/remove it from mine?

The name of the deck array is playerDeck.
To output a card I have been doing:
System.out.println ("Your card is the " + playerDeck.deck[c]);
c gets incremented by one each time through the while loop.
Let's say that I lose, that the opponents card is higher, how would I remove card "c" from the playerDeck array and add it to the opponents deck array, called compDeck?

I know I am new here, but I appreciate any help in this matter.
