In Java please!

Use ArrayList, no bufferedReader.

You have a file with multiple results from a survey. Write the following methods:

- Write a method getStats that takes Strings parameters and returns statistics for name/location/occupation: public SurveyStats getStats(String name, String location, String occupation)

- Write a method SurveyResult that returns an iterator for all survey results.

- Write a method getSurveyResults that accepts integers as parameters and returns an array of the results: public SurveyResult[] getSurveyResults (int index, int count)

- Write a method that accepts array of x and y values and returns the slope of the line: public double calcSlope(Integer[] x, Integer[] y)

- Write a method that accepts an array of readings and returns a slope of best fit line: public double calcSlope(Readings[] surveyReadings)
