Is this program alright?

Question

What I have to do is to create a program that asks the user how many legs there are in a farm of only cows and chickens. Then I have to tell him all the possible combinations of cows and chicken there could be in the farm.

For example, if the number is 6, there could be 1 cow and 1 chicken or 0 cows and 3 chickens. The number entered is always a multiple of 2

Answer 1

import javax.swing.JOptionPane;
public class Program
{
public static void main(String[] args) {
int i, totalTemp, nbCows, nbChickens, nbLegs;
do{
nbLegs = Integer.parseInt(JOptionPane.showInputDialog("total legs"));

}while(!(nbLegs%2==0));

i=0;
do{
totalTemp=nbLegs;
nbCows = nbLegs/(4*i);
totalTemp = nbLegs - nbVaches*4;
nbChickens=totalTemp/2;
System.out.println(nbCows + nbChickens);
i++;
}while(!(nbLegs==nbChickens*2));
}
}
