Dividing numbers with remainders showing
I am looking to Dividing numbers within java. the code that i have at the minute is
Java Code:public synchronized void setProduct (int number) { this.product = (number / number); }
Java Code:if (selection==2) { // Returing the sum of the numbers int i = 1; int number = 0; int sendNum = 0; do { System.out.println("Enter Number: " + i); String num = br.readLine(); sendNum = Integer.parseInt(num); stub.setProduct(sendNum); i++; }while(i<=4); number = stub.getProduct(); System.out.println("NUMBER " + number); }//end if

Please describe in words what you want to do.
From your code it's not clear what your program should do. Please describe your problem(s) in words.

I want the program to be able to divide numbers like 100/2/2/2 and then have it out put 12.5. I want to input the numbers tho and they will not be the same every time.

12.5? where is the remainder? 5 in .5 is a decimal number....
100/2 = 50
50/2 = 25
25/2 = 12.5
12 * 2 = 24
25  24 = 1
Your remainder is 1...
Java Code:int dividend = 100; int divisor = 2; int times = 3; int start = 0; while(start<(times1)){ dividend /= divisor; start++; } int final_quotient = 0; while(dividend>=divisor){ final_quotient++; dividend = divisor; } System.out.println("Quotient: "+final_quotient+" Remainder: "+dividend);

Use doubles or floats. the int data type is exactly that an Integer. Doubles have some decimal places and floats have even more.

By the way, my codes above is just based on calculation's flow....

I got it working my self. All i did was this.average += number;
this.average2 = average /4;
this allowed me to input any numbers that i like and also return numbers

I'm not clear what exactly you want to do. Are you try to find the sum of few numbers and then find the average? If so, how did you change the number of values?

The math package has divideAndRemainder() that does this. I made a short example, inputs are strings so you may have to jump through a few hoops.
<code>
import java.math.*;
public class divideWithRemainder
{
public static void main (String [] args){
// Create via a string, other options are available
BigDecimal num1 = new BigDecimal("1137");
BigDecimal num2 = new BigDecimal("83");
// an array to hold the result
BigDecimal[] num3 = new BigDecimal[2];
System.out.println ("divide " + num1 + " by " + num2 + " return both result and remainder");
num3 = num1.divideAndRemainder(num2);
System.out.println ("quotient = " + num3[0] + " remainder = " + num3[1]);
}
}
</code>
