    Default Can't find javaclass

    Hey guys, I have never had this error pop-up before compiling. It says it cannot find my javaaplication class...

    public static void main(String[] args)
    {
    double[] myList = { 5.0D, 4.4D, 1.9D, 2.9D, 3.4D, 2.9D, 3.5D };
    System.out.println("My list before sort is: ");
     
    printList(myList);
    bubbleSort(myList);
     
    System.out.println("My list after sort is: ");
    printList(myList);
    }
     
    static void printList(double[] list) {
    for (int i = 0; i < list.length; i++)
    System.out.println(list[i]);
    }
     
    static void bubbleSort(double[] list) {
    boolean changed = true;
    do {
    changed = false;
    for (int j = 0; j < list.length - 1; j++) {
    if (list[j] <= list[(j + 1)])
    continue;
    double temp = list[j];
    list[j] = list[(j + 1)];
    list[(j + 1)] = temp;
    changed = true;
    }
    }
    while (
    changed);
    }
    }

    Thanks for help

    --- Update ---

    package javaapplication18;
     
    /**
     *
     * @author Onlyname
     */
    public class JavaApplication18 {
     
        /**
         * @param args the command line arguments
         */
        public static double min(double[] array) {
            double[] myList = new double[10];
            java.util.Scanner input = new java.util.Scanner(System.in);
            System.out.print("Enter " + myList.length + " values: ");
            for (int i = 0; i < myList.length; i++)
                myList[i] = input.nextDouble();
            // TODO code application logic here
            double min = myList[0];
            for int(int i = 1; i < myList.length; i++){
                if (myList[i] > min) min = myList[i];
        }
            return min;
        }
    }

    Sorry first post was incorrect. This is the code with the problem.

    Always copy-paste the error message and post it with your code and question

    There's something wrong in that the compiler is looking for a class called "javaaplication", but the class in the code you posted is called JavaApplication18. There might also be an issue with the way you've set up the files in the package. We'll know more after you post the exact error message - the whole thing - copied and pasted.

    Are you running from the command line or in an IDE like Eclipse or Netbeans? If from the command line, paste the command you're using to compile the code.

    I am using the IDE Netbeans. I tried to load a picture but website, just goes to a white page for me.

    --- Update ---

    I found what I've done wrong. I took out the "public static void main(String[] args)" by accident, so it wasn't finding that class at all. I added that line back in and it seems to be giving me plenty of other errors. SO it is working haha. Thanks.
