public class CollectionsSortExample
{

    public static void main(String[] args)
    {
        ArrayList<Double> arrayList = new ArrayList<Double>();
        arrayList.add(1.4);
        arrayList.add(1.2);
        arrayList.add(1.3);
        arrayList.add(1.1);

        System.out.println("Before Sorting  : " + arrayList + "\n");

        /*
         * Sorts the specified list into ascending order, according to the
         * natural ordering of its elements.
         * 
         * All elements in the list must implement the Comparable interface.
         */
        Collections.sort(arrayList);

        System.out.println("After Sorting   : " + arrayList);

    }

}

Before Sorting  : [1.4, 1.2, 1.3, 1.1]

After Sorting   : [1.1, 1.2, 1.3, 1.4]
