Give me an example of Directions for completing and submitting the practice problems:

$$ Java source code should be in the following format: type your name, course number, section

number, and assignment number on the top of ALL files in comments.

$$ Place complete java files into a folder, named FirstInitialLastName$\_$Pra#$,$ compress the

folder as a zip file, and then submit.

$$ Upon submission, check solutions to the practice problems in the discussion board.

Practice Problems:

Please download the zip file, Module $4$ Student File, and unzip it$.$

$1.$ Open the incomplete program, DataStat.java and DataStatDriver.java.

The DataStat class will rearrange the data in DESCENDING order and calculate the

mean for the data set. The data member is data$[],$ which will references to a list of

scores $($any number of elements$).$

You need to complete the constructor, and other methods listed in the class diagram

$($All algorithms are in Module $4$ Lecture Notes, but you may need to modify code, like

array name, operators and so on$).$ Then complete method calls in DataStatDriver.java

to test the DataStat.java.
