   So am having a dilemma with my program that I created. I am a beginner programmer so please bare with me. This is my program with the directions in the comment:

   //*********Ask a user to enter a single four digit birthdate number representing the month and date he/she was born. ( Example if someone has a birthday of December 13 they would enter 1213)

   //Split the 4 digit birthdate into two 2 digit numbers. One contains the first two digits and the second the last 2 digits of the birthdate. (Example 12 and 13)

   //Divide the first 2 by the last 2 to get a quotient. (Example 12/13)

   //If the quotient is greater or equal to one- multiply it by a random integer in the range of 10 through 20 and display the result.

   //Otherwise add to the quotient a random integer in the range 30 through 40 and display the result.

   //Hint- to split the 4 digits remember your ISBN problem or day of week problem. Also- this should all be done as integer math.

   //Remember your prompts and output should be complete and explicit. – Kathy Ohaka*********//

   import java.util.Random;
   import java.util.Scanner;
   
   public class TestThreeKIO 
   {
   	public static void main(String[] args) 
   	{
   		int birthDate, month, day, q;
   
   		Scanner scan = new Scanner(System.in);
   		Random rand = new Random();
   
   		System.out.print("Enter a single four digit birthdate number representing the " +
   							"month and date you were born in. ( e.g. December 13 = 1213):");
   		birthDate = scan.nextInt();
   		month = birthDate / 100;
   		day = birthDate % 100;
   
   		q = day / month;
   		System.out.println(q);
   
   		if (q >= 1) {
   			birthDate *= rand.nextInt(11) + 10;
   			System.out.println(birthDate);
   		} else
   			System.out.println(q += rand.nextInt(11) + 30);
   	}
   }
   

   So…
   It is not written in the comments to do so, but for my sake, what I am doing is trying to find out if I am getting the right answer for the splitting of birthdate which is in the print line of line 26 (I think that it’s line number, you know where I am getting at). For example, If I am the user and my birthday is 0894 (Feb 8th), the console is suppose to print out after compiled and being ran:

   8
   94

   I am not getting that. I am getting other numbers which is not correct so when that number is being generated through the Random class, it’s wrong. So what is my error. Eventually, I will erase the print line because it is not needed. Plus the the if-else statement is not showing a result when I run it. What is my error there as well??

     I ran (debug) your program and it run perfectly. Try to run program in debug mode to see what is happening.
