Week 3: Objects, files and exceptions/16b. Players from FILE

@@ -0,0 +1,82 @@
+The file players.txt contains the names of the players, one name on each line.
+
+Write the method
+
+ArrayList<String> readPlayers()
+
+which reads the contents of the file and stores it in a list, 
+so that each name is one element in the list. 
+Finally, the list is returned.
+
+Use the Scanner class to read the file. 
+You can see a sample tutorial in the code above - 16a.
+
+
+
+An example of calling the method 
+(note that the test program will draw a new set of contents for the file at each run - so the output will vary):
+public static void main(String[] args){
+    ArrayList<String> list = readPlayers();
+    System.out.println(list);   
+}
+
+Example output:
+[Ann, Ann, Adam, Keith, Ann, Jane, Thomas, Jack]
