Neep help writing a program that multiplies digits?

I need help writing a java program that prompts a user to enter a number than adds each digit without using if and while statements. Example: I enter 987, the program should say this number has 3 digits, and multiply each digit to it's decimal place.

Like this

9*100

8*10

7*1

This is my code so far, I think I am on the write path,but don't know where to go from here.

public static void main(String[] args) {
   Scanner keyboard = new Scanner(System.in);
   System.out.print("Please enter number");
   int x;

  x= keyboard.nextInt();
  for(int i=1;i<=20;i++){
      System.out.print(x/1);
      System.out.print(x/10);
      System.out.print(x/100);
      System.out.print(x/1000);
      System.out.print(x/10000);
      System.out.print(x/100000);
  }
}

}
