Question

我正在学习Java并搜索了这个错误，这很常见。但我找不到解决方案。我试图重新使用finalScore的结果，但无论我如何声明它或放置它，IntelliJ都不会识别它。我知道我在这里遗漏了一些根本明显的东西。如何声明整数以便可以在不同的方法中重复使用它们？ gameOver方法之外的任何地方都是个问题。我也试过了public static int finalScore，但也犯了错误。并且calculateScore.finalScore但仍然是错误。

package com.test;

public class Main {

    public static void main(String[] args) {
        // write your code here



        calculateScore(true, 5, 5, 200, "sam");
        calculateScore(true, 5, 8, 200, "bob");
    }


    public static void displayHighScore(){


        if (finalScore > 100);           //problem line of code
        System.out.println("helloworld");
    }

    public static int calculateScore(boolean gameOver, int score, int levelCompleted, int bonus, String name) {

        if (gameOver) {
            int finalScore = score + (levelCompleted * bonus);
            finalScore += 2000;
            System.out.println("your final score was " + finalScore);
            return finalScore;

            if ((finalScore > 100) || (finalScore < 200));
            System.out.println( name "is in position 4");

        }
        return -1;    //if the above isn't required/doesn't run, this statement is:  else return -1
        //or we can just type is as } else { return -1;


        }
    }

这里的代码存在很多问题。但是对于您提到的问题，您需要将finalScore声明为全局static变量，如下所示

...
    static int finalScore;

    public static void main(String[] args) {
        // write your code here



        calculateScore(true, 5, 5, 200, "sam");
        calculateScore(true, 5, 8, 200, "bob");
    }
...

此外，您需要将return finalScore语句放在if(gameOver)块的末尾，如下所示，否则您将无法获得第if ((finalScore > 100) || (finalScore < 200));行的错误

if (gameOver) {
            finalScore = score + (levelCompleted * bonus);
            finalScore += 2000;
            System.out.println("your final score was " + finalScore);


            if ((finalScore > 100) || (finalScore < 200));
                System.out.println( name +"is in position 4");
            return finalScore;

        }
