Hello, this is my assignment that I need help with! :

Write a program that writes user supplied data to a text file and can perform a few statistical calculations on the data.

Constraints

The file directory will be C:/W12Assignment. Mac and Linux distro users can modify this location

Only one file will be created, used, and updated while the program runs

Requirements

Use exception handling and validation where appropriate

Use PrintWriter and Scanner for writing and reading data

Use a separate (external to the main class) subclass to write data

Use a separate (external to the main class) subclass to read data

Use a separate (external to the main class) subclass to validate entries

Use set and get methods in the subclasses

Find the average of all the numbers in the file

Find the smallest number in the file

Find the largest number in the file

Find the standard deviation (StdDev) of the number set (Follow the Basic Example as a model for your StdDev algorithm located here (Links to an external site.)Links to an external site..)

Implement a loop to run the program again if the user wishes (Note: this will only allow updates

or reading of the same file since only one file is used for duration of the program run)

Use the supplied MyNumbersLarge.txt file to make sure you are obtaining the correct information as such:

o All numbers printed (500 numbers) o The average of the numbers in file name is: 502.3212 o The smallest number in the file is: 1.2416 o The largest number in the file is: 999.3116 o The standard deviation for the numbers in this file is: 287.6556

This program will utilize code learned from Week 1 through Week 12

Hints

Consider using an ArrayList of Doubles to store numbers as they are entered

Research "Collections" to assist with minimums and maximums

Considering writing the code to work with all correct entries before implementing validation and exception handling. Once the code works, then try to break it with bad entries. This way, you can separate the requirements (Code in chunks!)

Make sure you use Java coding conventions
