	public static void main(String a[]){
		
		int[] myArr = {2,4,2,4,5,6,3};
		System.out.println("My array elements:\n");
		for(int num:myArr){
			System.out.print(num+"  ");
		}
		int[] newArr = Arrays.copyOfRange(myArr, 1, 4);
		System.out.println("\nMy new array elements:\n");
		for(int num:newArr){
			System.out.print(num+"  ");
		}

Can interface be final?
No. We can not instantiate interfaces, so in order to make interfaces useful we must create subclasses. The final keyword makes a class unable to be extended.
