// Create Stack object
Stack<Integer> stack = new Stack<Integer>();
     
//Take  User input from keyboard
 System.out.println("Enter any Decimal Number: ");
 int num = in.nextInt();
while (num != 0)
{
   int d = num % 2;
   stack.push(d);
   num /= 2;
 } 
 System.out.print("\nBinary is:");
while (!(stack.isEmpty() ))
 {

 }
System.out.println();
