Initailization

[Kartiky14]

if(y%4==0)
{
int day[]= {30,29,30,31,30,31,31,31,30,31,30,31}
else{
int day[]= {30,28,30,31,30,31,31,31,30,31,30,31};}
Can a array be initialized like the above way and then be used in a enhanced for loop somewhere in the program ?????

Did you try this code?What happened? What do you mean by "be used in a enhanced for loop"?

Yes i did and a compilation error popped...of the the array not been found at the looping statement
well i call this an enhanced for loop :P
for(int <initialization variable>:array)
{}

Here's more than enough to get you going in the right direction. The one thing you have to be cognizant of in taking this approach, is in what ways shallow or deep copying will affect the processing of your application.

start here:

	static Scanner console = new Scanner(System.in);
	public static void main(String[] args)
	{
		int y;
		
		System.out.println("Enter:");
		y = console.nextInt();
		
		int[] day = new int[0];
		if(y % 4 == 0)
		{
			int[] days = {1,2,3};
			day = days;
		}
		else
		{
			int[] days ={5,6, 7, 8, 9,0};
			day = days;
		}
		
		for(int n : day)
		{
			System.out.print(n + " ");
		}

	}

It means that your day array is not accessible within the for-each loop block. This is happen because your day variable is declared inside the if statement block. To let the for block have access to it, declare your array before the if block. You can the initialize it inside your if block and iterate it using the for-each statement.
