Question

Java BlackJack Game:

Help with 1-4 using the provided code below

1. Design First: Sketch on paper what you want the screen to look like. Draw it at the start of the game (empty card hands), and at the end of the hand (full card hands). Draw your linked lists. Draw pictures of what the linked lists will look like. Draw the lists at the start of the game (empty card hands), and at the end of the hand (full card hands). Finally write some pseudo code for the deal, the transfer of cards from the deck to the player(s) hand. 2. Use at least 3 linked lists in your design. For Blackjack to would be a deck, a dealer and a player linked list of cards. If you want to program a game with just 2 lists, you must get the instructors approval before you start coding. 3. Update the Card class for use in scoring. The card class must have member variables that allow you to determine the rank and/or the suit of the card. 4. Use the linked lists when displaying cards. When you show cards in a linked list use the following pseudo code to do it: current card list. first while (current card is NOT null) display current card on the screen current card current card.next =
