+Make a blackjack game, play against the computer-dealer. Aces are always, only, 1. 
+
+Writing a Blackjack program 
+
+Create a BlackJack class, with a runGame() method.
+
+1. Define your methods: 
+ - hit() or deal_card() 
+ - dealerDraw(dealerScore) 
+ - checkWin(dealerScore,playerScore) 
+ - isBust(score) 
+2. Make a variable called endGame and set it equal to False 
+3. Make a loop that only runs while endGame is False (i.e. the game has not ended) 
+4. Inside the loop, get input from the player to ask what he wants to do 
+  * If his input was “stick” 
+    * print out his total and the dealer’s total 
+    * check who has won and print it 
+    * end the game 
+  * If his input was “hit”: 
+    * draw him a new card and add it to his total 
+    * check if he has bust – if so the game ends and he loses, if not print his new total 
+    * if he didn’t bust, decide whether the dealer will draw 
+    * check if the dealer is bust – if so the game ends and the player wins 
+
+That’s all!

+```
+public int generateRandomInt() {
+    int min = 1;
+    int max = 10;
+    Random r = new Random();
+    return r.nextInt((max - min) + 1) + min;
+    }
+```
+
+You will have to put
+`import java.util.Random;` at the very top of your class file.
