COP3337 Fall 2018 Assignment 1

File I/O and ArrayList:

1) You need to read store the stock price contents Stock_Data.txt for each stock into an ArrayList. Heads up remembered that the stock data file has a header that you need to deal with. Note, you will find the Stock_Data.txt file in the data folder of the Netbeans skeleton project provided to you. Example: ArrayList x_stockPrices = new ArrayList();

2) Implement the following methods: public static double findAverage(ArrayList prices) public static double findStandardDeviation(ArrayList prices) public static double findCorrelation(ArrayList firstPrices, ArrayList secondPrices )

3) Create ArrayList that store each stock correlation values against the other stocks. Example: ArrayList xCorrelations = new ArrayList();

4) Create a 2D ArrayList called correlationMatrix at stores all the stock correlations Example: ArrayList> correlationMatrix = new ArrayList>();

5) Output the contents of the correlationMatrix to the console and print out the values.
