    Mutli-Dimensional Arrays

    Write a class (and a client class to test it) that encapsulates the evolution of the sales tax rates in the 50 U.S states over the last 10 years. Your only instance variable should be a two-dimensional array of values representing the sales tax rates. Dimension 1 represents the state and dimension2 represents the year. Your constructor can simply be a default constructor, randomly generating the sales tax rates, which should be between 0 and 0.06. You should include the following methods:

    a. A method returning the index of the state that has the biggest average tax rate over the years.

    b. A method returning an array of indexes of the states that have had at least one year with a tax rate less than 0.001

    c. A method returning the highest sales tax rate over the years for a given state (which will be a parameter)

    this was the question. please help. how can I solve it?
