working on a java program which involves multi-dimensional string array to quiz the user to match states to capitals

        // FIXME: Ask the user to guess the capitals for all 50 states, display one state at a time; Use for loop
        System.out.println("What is the capital for Delaware?");


        // FIXME: Modify the statement below to print total correct count
        System.out.println("Total correct count: 35");


    }

}

what i need is to figure out how to get this program to work as i am stumped and even my teacher doesnt know exactly how to solve this program

Reasons to downvote: **a)** We don't know what your exact problem is. **b)** you didn't explicitly ask a question. **c)** we're not going to fix your code for you when you haven't ran a debugger or told us what you've tried.. — Aaron Gillion, Apr 07 '16 at 00:28

Pick a random number from 0 to 49. This will let you choose which state you want to let the user guess the capital of.

// this should give you a number between 0 and 49. 
// [Someone, please correct me if the bounds are wrong.]
int randomRow = (int) ( Math.random() * (49+1) );

Now, the 0th index, i.e., stateCapital[randomRow][0] is the name of the state and the 1th index is the capital. Ask the user a question and read in his/her input using a Scanner. Compare the inputted answer to the 1th index.

I hope this will set you on the track to successfully complete your assignment. Let me know if there are any questions.
