Java - IntelliJ 提示缺少分号，但我不确定到底是什么问题

Question

我在学习 Udemy Java 类(class)时遇到了问题。我编写了下面的代码，因为类(class)主题是方法。 Hoverer，我不知道为什么它无法编译。有人可以帮我找出错误吗？

这是 IntelliJ 给我的错误:

public class Main {

public static void main(String[] args) {

    String playerName = "Piotr";

    int playerPosition = CalculateHighScorePosition(1500);
    displayHighScorePosition("Piotr", playerPosition);

    playerPosition = CalculateHighScorePosition(900);
    displayHighScorePosition("Cezary", playerPosition);

    playerPosition = CalculateHighScorePosition(400);
    displayHighScorePosition("Adam", playerPosition);

    playerPosition = CalculateHighScorePosition(50);
    displayHighScorePosition("Julia", playerPosition);

    private static void displayHighScorePosition(String playerName, int playerPosition) {
    System.out.println( playerName + " managed to get into " + playerPosition );

}

    private static int CalculateHighScorePosition(int playerScore) {
        if (playerScore > 1000) {
            return 1;
        }
        else if (playerScore > 500 && playerScore < 1000) {
            return 2;
        }
        else if (playerScore > 100 && playerScore < 500) {
            return 3;
        }
        else {
            return 4;
        }
    }

}
}

尽管我有更好的判断，但我还是回答这个问题。

您已在主方法中定义了两个方法。

public class Main {

  public static void main(String[] args) {

    String playerName = "Piotr";

    int playerPosition = CalculateHighScorePosition(1500);
    displayHighScorePosition("Piotr", playerPosition);

    playerPosition = CalculateHighScorePosition(900);
    displayHighScorePosition("Cezary", playerPosition);

    playerPosition = CalculateHighScorePosition(400);
    displayHighScorePosition("Adam", playerPosition);

    playerPosition = CalculateHighScorePosition(50);
    displayHighScorePosition("Julia", playerPosition);
  }

  private static void displayHighScorePosition(String playerName, int playerPosition) {
    System.out.println( playerName + " managed to get into " + playerPosition );
  }

  private static int CalculateHighScorePosition(int playerScore) {
    if (playerScore > 1000) {
        return 1;
    }
    else if (playerScore > 500 && playerScore < 1000) {
        return 2;
    }
    else if (playerScore > 100 && playerScore < 500) {
        return 3;
    }
    else {
        return 4;
    }
  }

}
