    If array variable v consists of type A[] (where A is a reference type) then v might hold a reference to any array type B[] instance.( provided that B could be assigned to A).

    Java Code:
    class Point { int x, y; }
    class ColoredPoint extends Point { int color; }
    class Test {
    	public static void main(String[] args) {
    		ColoredPoint[] cpa = new ColoredPoint[10];
    		Point[] pa = cpa;
    		System.out.println(pa[1] == null);
