Arrays Sort Test

CODE

java.util.Arrays;

class ArraysSortTest
{
    public static void main(String arg[])
    {
        int sample[] = {5, 1, 8, 2, 4, 3, 7, 6, 10, 9};
        Arrays.sort(sample, 3, 8); // LINE A
        System.out.print("Array after sorting within specified range is: ");
        for (int temp : sample)
        {
            System.out.print(temp + " ");
        }
        Arrays.sort(sample); // LINE B
        System.out.println();
        System.out.print("Array after sorting all elements is: ");
        for (int temp : sample)
        {
            System.out.print(temp + " ");
        }    
    }
}

OUTPUT

Array after sorting within specified range is: 5 1 8 2 3 4 6 7 10 9
Array after sorting all elements is: 1 2 3 4 5 6 7 8 9 10

DESCRIPTION

At LINE A, the array is sorted in the range [3, 8) i.e. inclusive lower limit and exclusive upper limit. The elements after sorting in the specified range are printed. At LINE B the whole array is sorted. The elements after sorting are printed.

THINGS TO TRY

Try changing the sorting range at LINE A. Consider cases like fromIndexgreater than toIndex, fromIndexequal to toIndexand index values out of bounds.

Try sorting double array or float array or String array.
