Homework - Mutli-Dimensional Arrays

Hey everyone, I could use some help with a homework problem that i am not understanding. Here is the problem:

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)


so far i have:

public Taxes()
{
Random random = new Random();
for (double i = 0; i < 50; i++)
{
for (double j = 0; j < 10; j++)
{
taxRate[i][j] = random.nextDouble( 0.06);
}
}
}

which doesn't even work. If i could get help with what I have and an idea for the three methods that would be awesome. Thanks guys!!

This will work if you define taxRate.

The statement of the problem seems pretty straightforward.

Where are you having a problem with it?

Is it in what is being asked or the code?
