Java Tutorial : Java Array (double values)
ArrayDemo.java
class ArrayDemo
{
    public static void main(String[] args)
    {
        // declares an array of doubles
        double[] doubleArray;

        // allocates memory for 10 doubles
        doubleArray = new double[10];

        // initialize first element
        doubleArray[0] = 10.2;
        // initialize second element
        doubleArray[1] = 20.3;
        // and so forth
        doubleArray[2] = 30.8;
        doubleArray[3] = 50.8;
        doubleArray[4] = 90.9;
        doubleArray[5] = 100.8;
        doubleArray[6] = 23.5;
        doubleArray[7] = 99.9;
        doubleArray[8] = 88.4;
        doubleArray[9] = 97.8;

        System.out.println("Element at index 0: " + doubleArray[0]);
        System.out.println("Element at index 1: " + doubleArray[1]);
        System.out.println("Element at index 2: " + doubleArray[2]);
        System.out.println("Element at index 3: " + doubleArray[3]);
        System.out.println("Element at index 4: " + doubleArray[4]);
        System.out.println("Element at index 5: " + doubleArray[5]);
        System.out.println("Element at index 6: " + doubleArray[6]);
        System.out.println("Element at index 7: " + doubleArray[7]);
        System.out.println("Element at index 8: " + doubleArray[8]);
        System.out.println("Element at index 9: " + doubleArray[9]);

    }
}
Output
Element at index 0: 10.2
Element at index 1: 20.3
Element at index 2: 30.8
Element at index 3: 50.8
Element at index 4: 90.9
Element at index 5: 100.8
Element at index 6: 23.5
Element at index 7: 99.9
Element at index 8: 88.4
Element at index 9: 97.8

Output
-------------------------------------------------------
Using for each loop get all elements from doubleArray
