This is a beginning Java Program

Write an application called PracticeArithmeticOperators.java that inputs one number consisting of five digits from the user, separates the number into its individual digits and prints the digits separated from one another by five spaces each. For example, if the user types in the number 49872, the program should print

4 9 8 7 2

The errors exist on all the lines with calculation, I continue to get :The operator % is undefined for the argument type(s) String, int : I have tried changing number to an integer but when I do this I get an error in my JOption Pane statement can someone please assist me with this.
Thank you
number/10000;
(number%10000)
(number%10000)
(number%10000)
(number%10000)

You cannot truncate a string using the modulus operator. That's for numerical data types only.
You only need one variable to do this assignment. Also, the assignment wants you to take user input, not hard code it in the program.

The Scanner class will come in handy here:

Scanner in = new Scanner(System.in);
// input the user's number as a string
String n = in.nextLine().trim();

Now you have a number in string format.
Next you want to output each digit using the substring() method of the String class.

// Since you probably haven't learned loops yet:
String space = "     ";
System.out.println(n.substring(0,1) + space);
// continue...
System.out.println(n.substring(4,5));
