    Default A problem in practicing the array

    The question is :ask the array size
    allocate space call method1
    ask user for a four digit number
    Method 1: filled up the array with four digit random number
    Method 2: check if the number is in the array
    call method 2 display if the number user input is in the array and at which array

    My job stops at:
    import javax.swing.JOptionPane;

    public class inClassArray

    public static void main(String[] args)

    double[] array;

    String arraySizeString = JOptionPane.showInputDialog(null,"Please enter the size of array:");

    int arraySize = Integer.parseInt(arraySizeString);

    String num1String = JOptionPane.showInputDialog(null,"please enter a four-digit number:");

    double num1 = Double.parseDouble(num1String);

    for(int i = 0; i < arraySize; i++)
    String stringRandomNum= JOptionPane.showInputDialog(null,"Please input the four-digit number to allocate in the array" + (i+1));

    array[i] = Double.parseDouble(stringRandomNum);

    public static double sameNum(double[] array)
    for ( int i = 0; i < arraySize; i ++ );
    num1 = array[i];
