        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");


    }

}

我需要的是找出如何使这个程序工作，因为我很难过，甚至我的老师也不知道如何解决这个程序

Answer 1

从0到49中选择一个随机数。这样您就可以选择让用户猜测其资本的状态。

// 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) );

现在，第0个索引，即stateCapital[randomRow][0]是州的名称，第1个索引是大写。询问用户问题并使用$push读取他/她的输入。将输入的答案与第1个索引进行比较。

我希望这会让您顺利完成作业。如果有任何问题，请告诉我。
