java - java中的数组循环

Question

我尝试主要使用数组来编写此代码。我试图在每个问题后显示“正确”或“不正确”，并在最后获得正确/不正确的答案总数。目标是使用数组来完成此任务，但我不知道如何使用数组在每个问题后显示正确/不正确。

//Declarations
String rightAnswer[] = { "B", "C", "A" };
String userAnswer[] = new String [3];
String answer;
int counter;
int finalInt = 3;
int index = 0;
int correct = 0;
int incorrect = 0;

// detailedLoop
for(index = 0; index < finalInt; index++) {
    do {
        answer = JOptionPane.showInputDialog("What planet has the largest rings? \n\nA. Neptune \nB. Saturn \nC. Jupiter");
        userAnswer[index] = answer;
    } while(!(answer.equals("A")|| answer.equals("B") || answer.equals("C")));

    index++;
    do {    
        answer = JOptionPane.showInputDialog("What planet has a large redspot? \n\nA. Neptune \nB. Saturn \nC. Jupiter");
        userAnswer[index] = answer; 
    } while(!(answer.equals("A")|| answer.equals("B") || answer.equals("C")));

    index++;
    do {
        answer = JOptionPane.showInputDialog("What planet is farthest from the sun? \n\nA. Neptune \nB. Saturn \nC. Jupiter");
        userAnswer[index] = answer;
    } while(!(answer.equals("A")|| answer.equals("B") || answer.equals("C")));

    if(userAnswer[index].equals(rightAnswer[index])) {
        System.out.println("Correct!");
        correct++;
        index++;
    }
    if(!(userAnswer[index].equals(rightAnswer[index]))) {
        System.out.println("Incorrect. The right answer is " + rightAnswer[index] + ".");
        incorrect++;
        index++;
    }
}
System.out.println("Total correct:" + correct + ". Total incorrect: " + incorrect + ".");

感谢任何帮助，谢谢。

这可能是您想要做的，再次，我不完全理解这个问题:

String questions[] = {
    "What planet has the largest rings? \n\nA. Neptune \nB. Saturn \nC. Jupiter",
    "What planet has a large redspot? \n\nA. Neptune \nB. Saturn \nC. Jupiter",
    "What planet is farthest from the sun? \n\nA. Neptune \nB. Saturn \nC. Jupiter"
};
String rightAnswer[] = { "B", "C", "A" };
String answer = null; // the user's answer
for (int i = 0; i < questions.length; i++) {
    do {
        answer = JOptionPane.showInputDialog(questions[i]);
    } while (!(answer.equals("A")|| answer.equals("B") || answer.equals("C")));
    String x = (answer.equals(rightAnswer[i])) ? "correct" : "incorrect.\nThe correct answer was " + rightAnswer[i];
    JOptionPane.showMessageDialog(null, "Your answer was " + x + ".");
}

请原谅我的风格。
