<identifier>期望-缩进？

Question

public class CoinFlip {
        public static void main(String[] args) {
            //Get a random number
            //Decide the outcome of the coin flip
            //Get a second random number
            //Decide the outcome of a second coin flip
            //Print out which flip had a higher score
            //Print out the maximum of the two flips
            double myNumber;

            myNumber = Math.random();
        int score;
        if (myNumber < .4) {
                System.out.println("heads");
                score = 5;
        }
        else if (myNumber <.8) {
                System.out.println("tails");
                score = 2;
        }
        else if (myNumber <.85) {
                System.out.println("derr");
                score = 20;
        }
        else {
                System.out.println("go 2 sleep");
                score = -3;
        }

        System.out.println("arrgh the score for der flip wus: " + score);

        }
        public static int max(int a, int b);
            int a = score;
            int b = secondScore;
                int maxScore = Math.max(score, secondScore);
                    System.out.println(score, secondScore);
        {

        }

我得到了int a和int b的预期错误，这是缩进吗？我不知道该怎么办。我试着在凹痕和托架周围移动，但没有结果。我是新来的，我很困惑。我觉得这是个很简单的问题。

Answer 1

缩进只对可读性很重要。你有三个问题我看得出来：

1. 整个类都没有“}”的结尾
2. max()方法是一个定义，在它之后不应该有';‘
3. 将max方法中的开头“{”移至该方法的逻辑上方。

希望这能有所帮助。

Answer 2

public class CoinFlip {
    public static void main(String[] args) {
        // Get a random number
        // Decide the outcome of the coin flip
        // Get a second random number
        // Decide the outcome of a second coin flip
        // Print out which flip had a higher score
        // Print out the maximum of the two flips
        double myNumber;

        myNumber = Math.random();
        int score;
        if (myNumber < .4) {
            System.out.println("heads");
            score = 5;
        } else if (myNumber < .8) {
            System.out.println("tails");
            score = 2;
        } else if (myNumber < .85) {
            System.out.println("derr");
            score = 20;
        } else {
            System.out.println("go 2 sleep");
            score = -3;
        }

        System.out.println("arrgh the score for der flip wus: " + score);

    }

    public static int max(int score, int secondScore) {
        int a = score;
        int b = secondScore;
        int maxScore = Math.max(a, b);
        System.out.println("Score 1 = " + score + " Score 1 = " + secondScore);
        return maxScore;

    }
