Java questions

How would I go upon doing these?

This all goes under a class named boggle.

Create member variables of type:

ArrayList of class String // stores data from data file with dice data

String // set to the name of input file BoggleData.txt

ArrayList of class String // stores data from data file with dictionary data

String // set to the name of input file Dictionary.txt

Method main() should:

Instantiate an instance of class ReadDataFile passing the file name variable for file BoggleData.txt as an argument

Call method populateData on the above object

Instantiate an instance of class ReadDataFile passing the file name variable for file Dictionary.txt as an argument

Call method populateData on the above object

Instantiate an instance of class Board passing as arguments method call getData on each of the two ReadDataFile object references from above

Call method populateDice on object reference of class Board

Output to the IDE output window the number of objects in the ArrayList of type String that stores the dictionary data
