这是我现在的进度。我真的很感激一些帮助。我这样做只是为了练习,但我真的希望这个程序尽可能详细和简洁。我正在学习,所以欢迎任何建议。我读到我需要解析字符串以给它们一个整数值,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
try {
Thread.sleep(2000);
}catch(InterruptedException ex) {
Thread.currentThread().interrupt();
}
//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!");
}
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();
}
//Question 2
System.out.println("What is the World's current population?");
String questionTwo;
questionTwo = scan.nextLine();
if(questionTwo.equalsIgnoreCase("7 billion")){
System.out.println("Correct!");
}
else
System.out.println("Incorrect. The answer was: 7 billion");
System.out.println("Next Question");
try {
Thread.sleep(2000);
}catch(InterruptedException ex) {
Thread.currentThread().interrupt();
}
//Question Three
System.out.println("Why is the sunset blue on Mars?");
String questionThree;
questionThree = scan.nextLine();
if(questionThree.equalsIgnoreCase("Distance from the sun causes the sunlight to lose intensity"))
{
System.out.println("Correct!");
}
else
System.out.println("Incorrect. The answer was: Distance from the sun causes the sunlight to lose intensity");
System.out.println("Next Question");
try {
Thread.sleep(2000);
}catch(InterruptedException ex) {
Thread.currentThread().interrupt();
}
//Question Four
System.out.println("What mobile carrier is the most popular in the United States?");
String questionFour;
questionFour = scan.nextLine();
if(questionFour.equalsIgnoreCase("Verizon Wireless")){
System.out.println("Correct!");
}
if(questionFour.equals("Verizon")){
System.out.println("Correct!");
}
else
System.out.println("Incorrect. The answer was: Verizon Wireless");
System.out.println("Next Question");
try {
Thread.sleep(2000);
}catch(InterruptedException ex) {
Thread.currentThread().interrupt();
}
//Question Five
System.out.println("What is the most popular television show today?");
String questionFive;
questionFive = scan.nextLine();
if(questionFive.equalsIgnoreCase("The Big Bang Theory")){
System.out.println("Correct!");
}
else
System.out.println("Incorrect. The answer was: The Big Bang Theory");
System.out.println("End of Trivia Part 1");
}
}
最佳答案
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;
每次用户得到正确答案时,您就将变量加 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,当程序结束时,您将像这样显示分数:
System.out.println("Your score: " + correctCount + "/5");
关于java - 是否可以对我的测验实现评分系统?我希望测验结束后显示 5 分制的分数,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/32515551/
