I need to preface this with I am not allowed to use an IDE in class, I must use TextPad to compile and run.

I am getting the following errors:

F:\Java\Lab 3\AveragesLab.java:63: error: class, interface, or enum expected public static double averageDbl (double[] arrayDbl) ^ F:\Java\Lab 3\AveragesLab.java:66: error: class, interface, or enum expected double average = 0.0; ^ F:\Java\Lab 3\AveragesLab.java:68: error: class, interface, or enum expected for(int i = 0; i < array.length; i++) ^ F:\Java\Lab 3\AveragesLab.java:68: error: class, interface, or enum expected for(int i = 0; i < array.length; i++) ^ F:\Java\Lab 3\AveragesLab.java:68: error: class, interface, or enum expected for(int i = 0; i < array.length; i++) ^ F:\Java\Lab 3\AveragesLab.java:71: error: class, interface, or enum expected } ^ F:\Java\Lab 3\AveragesLab.java:73: error: class, interface, or enum expected return average; ^ F:\Java\Lab 3\AveragesLab.java:74: error: class, interface, or enum expected } ^ 8 errors Tool completed with exit code 1

Code

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.print ("Enter 10 integers or whole numbers, for example 75: "); // Create the integer array int arrayInt [] = new int [10]; for (int i = 0; i < arrayInt.length; i++) { arrayInt [i] = input.nextInt(); } int averageInt = average (arrayInt); System.out.println ("\nThe average of the intger array is: "+averageInt); System.out.println (); System.out.println (); // Receive the double values System.out.println ("Enter 10 double amounts including decimals, for example 75.5: "); // Create the double array double arrayDbl [] = new double [10]; for(int i = 0; i < arrayDbl.length; i++) { arrayDbl [i] = input.nextDouble(); } double average = averageDbl (arrayDbl); 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; } }

The error is below this line

 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; } }

There is a closing } too much before public static double averageDbl. I saw that average had one too much.

With that the class is closed, and the compiler expects another class/interface.

The array var in averageDbl doesn't exist. Make the three occurances into arrayDbl.

I changed all the array to arrayDbl and the error is still there.
I took your code from the two sections into Eclipse, made the changes I recommended, and it compiled fine. Is there any code between the two sections? If so, then there is a syntax error there. Probably an extra brace?

Assuming you have posted all the code and just split it with the comment about "error is below this line" in half, your parenthesis are not matching.
So " public static double averageDbl (double [] arrayDbl)" is defined outside the class.

This is better:
