Java 我的测验可以实行计分制吗？我想在测验结束后显示5分的分数

这是我现在的进步。我真的非常感谢你的帮助。我这样做只是为了练习，但我真的希望这个程序尽可能的详细和简洁。我正在学习，所以我欢迎任何建议。我读到我需要解析字符串来给它们一个整数值，但我不知道如何去做

import java.util.Scanner;

public class TriviaPart1 {
public static void main(String[] args) {
    //Trivia Questions:
    Scanner scan = new Scanner (System.in);

    System.out.println("Welcome! Time to begin some trivia");
    //The program pauses for 2 seconds before asking the first question

我可以在这方面给你一些指导，但实际的实现取决于你。你可以声明一个全局变量，并在答案正确时使其递增 例如：

---

在此之后，您可以使用

i

的值来显示您的答案。

在程序开始时，您应该声明一个名为

correctCount

的变量，如下所示：

int correctCount = 0;

System.out.println("Your score: " + correctCount + "/5");

每次用户得到正确答案时，向变量中添加1：

//Question 1
System.out.println("Who holds the world record for running the fastest 100 meter dash?");

String questionOne;
questionOne = scan.nextLine();

if(questionOne.equalsIgnoreCase("Usain Bolt")) {
    System.out.println("Correct!");
    correctCount++; //here you increase the variable by one.
}
else 
    System.out.println("Incorrect. The answer was: Usain Bolt");
    System.out.println("Next Question");

    try {
        Thread.sleep(2000);
        }catch(InterruptedException ex) {
            Thread.currentThread().interrupt();
        }

现在，当节目结束时，您可以如下显示分数：

int correctCount = 0;

System.out.println("Your score: " + correctCount + "/5");
