如何在 dr Java 程序中创建计数器

/*This is a quiz program that will ask the user 10 questions. the user will answer
 * these questions and will be scored out of 10.*/

class Quiz {
    public static void main(String args[]) {
        // Instructions
        System.out.println("instructions");
        System.out.println(" ");
        System.out
                .println("1. You wll be asked ten questions through out the quiz.");
        System.out
                .println("2. The first question will appear, you will have to answer that question for the next question to appear.");
        System.out
                .println("3. When you answer the last question you will be told your score.");
        System.out.println(" ");

        System.out.println("welcome to the basketball quiz.");

        // question 1
        System.out.println(" ");
        System.out.println("Question 1. ");
        System.out.println("How tall is a basketball hoop? ");
        System.out.println("Type in Answer here:");
        String Question1 = In.getString();
        if (Question1.equalsIgnoreCase("10 Feet")) {
            System.out.println("Correct!");
        } else {
            System.out.println("you got this questions wrong");
        }

        // question 2
        System.out.println(" ");
        System.out.println("Question 2. ");
        System.out.println("Who invented basketball? ");
        System.out.println("Type in Answer here:");
        String Question2 = In.getString();
        if (Question2.equalsIgnoreCase("James Naismith ")) {
            System.out.println("Correct!");
        } else {
            System.out.println("you got this questions wrong");
        }
    }
}

这是我正在编写的程序。我想制作一个计数器，对每个正确回答的问题进行评分，然后在问题完成后将其显示给用户。我尝试使用这个：

int score=0;

score=score+1;

它不适用于第二个问题，但适用于第三个问题......它给了我一个错误。 我还有其他方法可以做到这一点还是我做错了什么？

看来您走在正确的轨道上。您需要在程序开头声明一个分数变量。

int score = 0;

然后，在打印出“正确”的每个问题中，您可以像这样增加分数：

 score++;

在程序结束时，在最后一个问题之后，您可以打印分数。

也许您应该发布尝试时遇到的错误。

UPDATE:语法是score++ 而不是score=++。即去掉=号。
