Blackjack (part 2)

In part 1, you wrote the logic for starting the game.

In part 2, you will write the logic for playing the game. Recall:

• First, it's the player's turn. The player can decide to hit or stay.

  • hit: draw another card.

  • stay: do nothing.

• If the player decides to hit, and their hand value exceeds 21, they go bust (lose).

• Once the player decides to stay, the dealer reveals the hidden card.

• Then, the dealer must hit until their total gets to 17. At 17 points or higher, the dealer's turn ends.

• You win if your hand value is higher than the dealer's hand.

• You win if the dealer goes bust (exceeds 21)

• You lose if the dealer's hand value is higher than yours.

Final output:

Task 7

---

Make a function that asks the user to hit or stay.

/**
 *  Function name -- hitOrStay
 *  @return (String)
 *
 * Inside the function:
 *   1. Asks the user to hit or stay.
 *
 *   2. If the user doesn't enter "hit" or "stay"
 *       Run a while loop
 *       During each run, println: Please write 'hit' or 'stay'
 *
 *   3. Returns the user's option
 */

If the user doesn't enter "hit" or "stay", keep asking them to try again by printing:

"Please write 'hit' or 'stay'"

The condition for this while loop is kind of tricky. I recommend using a while loop that runs forever and breaking it when it's appropriate. Test your function by calling it from main().

Task 8

---

In Task 8, you will keep asking the player to hit or stay. In other words, make a while loop that runs forever. Then, call your function inside the while loop. Every time the player hits, draw a new card and calculate their new total. Then, print:

• (new line) You get a (new line) <show new card>

• your new total is <total>

• Once the player 'stays', break the loop.

Task 9

---

While the player is hitting, if they go bust (total exceeds 21) print: "Bust! Player loses". Then, shut down the game with System.exit(0) (System.exit(0) terminates execution).

Task 10

---

After the player chooses to stay, it becomes the dealer's turn. First, reveal the dealer's hidden card.

Print:

• (new line) Dealer's turn

• (new line) The dealer's cards are (new line) <dealer card 1> (new line) and a (new line) <dealer card 2>

Task 11

---

The dealer must keep "hitting" until their total gets to 17. Every time the dealer hits, print:

• (new line) Dealer gets a (new line) <show new card>

• (new line) Dealer's total is <dealer's total>

At 17 points or higher, end the dealer's turn.

Task 12

---

If the dealer's total is higher than 21, print: "Bust! Dealer loses" and end the game with System.exit(0).

Task 13

---

If at this point, the program didn't terminate, compare the dealer and player's hand values.

• If the player's hand value is higher, print: Player wins!

• Otherwise, print: Dealer wins!.

Final output:

Good luck!
