Integers - Position

I have an integer called "numb" which has the value of 155.

Is there a way to split the integer up like you can with strings? With strings you can have substrings. Can I do the same thing with an integer? I need to write a recursive method that writes the value backwords. Any help you can offer is appreciated.

Thanks.

If you have a string reversing function already, you can convert a number to a string by simply appending an empty string, ie...

Code:

---

String s = 155 + ""; // s = "155"

---

:)

or:

Code:

---

String s = Integer.toString (numb);

---

and then proceed as before

Well you could cheat and use StringBuffer

Code:

---

public class TestString{
  public static void main(String args[]){
    StringBuffer buf = new StringBuffer("Beres");
    System.out.println(buf.reverse());
  }
}

---

or you could also just write one yourself

Code:

---

public String reverseRecurse(String inStr) {
    String outStr = new String();
    if (inStr.length() > 0 ) {
      outStr = inStr.charAt(inStr.length()-1) + reverseRecurse (inStr.substring(0, inStr.length()-1));
    }
    return output;
}

i dont have java at work to test this but I think it should work beautifully.

also, you may want to do this mathematically. It should have better performance for you. This could be done by taking the modulus of the number and using division, but I will let you think of this one, hate to have the teacher think you know everything :)
