Java 将从程序接收的输入从int更改为string初学者

我写了一个模拟评分测验的程序，但是我想把我收到的输入从int改为string，这样我就可以输入a，b，c，d作为测验的答案。我该怎么做

import java.util.Scanner;
public class Quizzes1
{
    public static void main(String[] args)
    {

        int Questions;
        int answers;
        int Quizzes;
        int numOfQs = 0;
        String phrase= "";
        Scanner scan = new Scanner(System.in);

        System.out.println("How many questions are in the quizz?");
        Questions = scan.nextInt();

        char[] key = new char[numOfQs];

        int[] canswers = new int[Questions];
        for (int i=0; i<canswers.length; i++)
     {
  System.out.println("Please give the correct answers " + (i+1) + ": ");
  canswers[i] = scan.nextInt();
     }

        while (!phrase.equals("n"))
        {

            double Correct = 0;
            double Incorrect = 0;
            for (int i=0; i<canswers.length; i++)
            {
            System.out.println("What are the answers that the students put");
            answers = scan.nextInt();
            if (answers == canswers[i])
                Correct++;
            else
                Incorrect++;
            }

            System.out.println("There are " +Correct + " correct answers and " +Incorrect
                +" incorrect answers");
            double Percent = ((Correct / (Correct + Incorrect)) * 100);
            System.out.println("The percentage correct is " +Percent +"%");
            phrase = scan.nextLine();
            System.out.println("Would you like to grade another quiz y/n");
            phrase = scan.nextLine();
        }
    }
}

import java.util.Scanner；
公开课测验1

公共静态void main（字符串[]args）

智力问题；
int答案；
智力测验；
int numOfQs=0；
字符串短语=”；
扫描仪扫描=新扫描仪（System.in）；
System.out.println（“测验中有多少问题？”）；
问题=scan.nextInt（）；
char[]key=新字符[numofq]；
int[]canswers=新int[问题]；
对于（inti=0；i因为a、b、c和d是单字母，为什么不读字符而不是int或甚至字符串呢

试试看

scanner.nextLine().charAt(0);

使用字符，您仍然可以使用代码的这一部分：

if (answers == canswers[i])
    Correct++;
else
    Incorrect++;
}

这与dasblinkenligh的答案非常相似
