Question

Can someone help with the java code?

(A city data file)

-----------------------------------------------------------------------------

Louisiana

6387 21.7 19 24.4 30.0264774449 -90.2425907379 1

------------------------------------------------------------------------------

Data in these city files is organized as follows:

i. Line one contains the name of the state of the city.

ii. Line two contains the abbreviation of the state of the city.

iii.Line three contains the name of the city.

iv. Lines four and all the lines that follow are organized in fields of numbers, each separated by a single space, essentially making columns of data in the file. These fields are:

A. field 1: sample size int; the number of people in the area sampled

B. field 2: percentage double; the percent result of the survey; stored in the form ##.# (example 50.2 is 50.2 percent)\

C. field 3: lower confidence double; the lower bounds of confidence in the percentage; stored in the form ##.# (example 50.2 is 50.2 percent)

D. field 4: upper confidence double; the upper bounds of confidence in the percentage; stored in the form ##.# (example 50.2 is 50.2 percent)

E. field 5: latitude central latitude of the sample area

F. field 6: longitude central longitude of the sample area

G. field 7: measure key the code (key) of the measure of the survey results

Make a class to hold one line of survey data for a city.

1. The survey data is found on lines four to a city file’s end.

2. This will be an immutable class. This means it has no setter (mutator) methods, only fields, constructors and getter (accessor) methods.

3. Create the class and file in the project as usual, then (a) add a private field for each of the seven fields on line four (and beyond) of a city file as described above (b) Add a constructor that accepts the values for the fields and assigns valid values. The limits are as follows. i. sample size must be 0 or greater ii. percentage, lower confidence and upper confidence must be in the range [0, 100], i. e. 0 to 100 inclusive iii.latitude must be in the range [25,50], i. e. 25 degrees north to 50 degrees north to belong to a city in the “lower 48” states iv. longitude must be in the range [-65,-130], i. e. -65 degrees to -130 degrees to belong to a city in the “lower 48” states; negative longitudes indicate west of the prime meridian v. measure key must be a value in the range [1,28], i. e. 1 to 28 inclusive (c) create a getter (accessor) for each of the private data fields (d) as a parametrized constructor exists, a default constructor must be created, even if it is empty of any code
