you need to iterate through the array in reverse order, that is start from the last element which is at index array.length-1 to 0

for(int i = array.length-1; i >= 0; i--)
	System.out.print(array[i] + " ");

hope this helps

I am still having some difficulties. I added the code you suggested, but I did not get any additional output from what I was seeing before. It just gives me what the conversion is doing, but it does not show me the final line of output I need that should say "Therefore, the binary value of n is (and then the binary value)." Here is my output and then my code after that. Please help. Thanks!
run:
Please enter the starting number:
250
Decimal 250 divided by 2 equals 125 with a remainder of: 0
Decimal 125 divided by 2 equals 62 with a remainder of: 1
Decimal 62 divided by 2 equals 31 with a remainder of: 0
Decimal 31 divided by 2 equals 15 with a remainder of: 1
Decimal 15 divided by 2 equals 7 with a remainder of: 1
Decimal 7 divided by 2 equals 3 with a remainder of: 1
Decimal 3 divided by 2 equals 1 with a remainder of: 1
Decimal 1 divided by 2 equals 0 with a remainder of: 1

so what exactly do you want to do? coz i didnt understand

[mostyfriedman]

ok, i think this is what you want

import java.util.Scanner;
public class Player
{
	public static void main(String[]args)
	{
		Scanner sc = new Scanner(System.in);
		System.out.println("enter a decimal number to convert");
		int n = sc.nextInt();
		String s = "";
		while(n != 0)
		{
			System.out.println("Decimal value " + n + " divided by 2 equals " + (n/2) + " with a remainder of " + (n%2)); 			
			s = (n%2) + s;
			n = n/2;
		}
		System.out.println("thus the binary value is " +s);
	}
}
