なぜ列挙エラーが発生しますか？

Question

私はクラスでIDEを使用することを許可されていないので、これを前にする必要があります。私は、コンパイルして実行するにはTextPadを使用する必要があります。

私は、次のエラーを取得しています：

F:\Java\Lab 3\AveragesLab.java:63: error: class, interface, or enum expected 
    public static double averageDbl (double[] arrayDbl)

コード

import java.util.Scanner; 

public class AveragesLab 
{ 
public static void main (String[] args) 
    { 

    // Create a scanner 
    Scanner input = new Scanner(System.in); 

    // Receive the integer values 
    System.out.print ("In this exercise you will be asked to enter a series of 10 numbers, twice.\n The first set will be integers or whole numbers and the second set will be doubles or \n numbers with a decimal. Please press the enter key after each number.\n");

     System.out.println(); 


     // Receive the double values

     // Create the double array 
     double arrayDbl [] = new double [10];

     System.out.printf ("%7.2f\nThe average of the doubles array is: "+average); 
     System.out.println(); 
     System.out.println(); 
    } 


    public static int average (int [] array) 
     { 
     int sum = 0; 
     int average = 0; 
     for (int i = 0; i < array.length; i++) 
     { 
     sum = sum + array [i]; 
     } 
     average = sum/array.length; 
     return average; 
     } 
    } 

エラーaverageDblでarray varが存在しない

public static double averageDbl (double [] arrayDbl) 
    { 
    double sum = 0.0; 
    double average = 0.0; 

    for(int i = 0; i < array.length; i++) 
    { 
     sum = sum + array [i]; 
    } 
    average = sum/array.length; 
    return average; 
    } 

} 

Answer 1

public static double averageDblの前に閉鎖}が多すぎます。 averageにはあまりにも多くのものがあった。

これでクラスは閉じられ、コンパイラは別のクラス/インタフェースを期待しています。

Answer 2

この線より下にあります。 3つの出現をarrayDblにします。

Answer 3

すべてのコードを投稿し、「エラーがこの行の下にある」というコメントを半分に分けていると仮定すると、かっこは一致しません。
"public static double averageDbl（double [] arrayDbl）"はクラスの外で定義されています。

Answer 4

これは良いです：
