Question

Thanks in advance.
In Java.
I'm having an issue with one of my methods.
Ex:

The array being pass in is a character array with element: w, ' ', K, Q, k, q, ' ', -, ' ', 0, ' ', 1

public class Find
{
public void enPassant(char[] array)
{
  for(int i = 0; i < array.length; ++i)
{
if(array[i] == 'e')
{
count = i;
}
else
{
count += 0;
}
}
  
if(count > 0)
{
System.out.println("En passant: " + array[count] + array[count + 1]);
}
  
if(count == 0)
{
System.out.println("En passant: none");
}
}

public class Main
{
public static void main(String[] args)
{
Find testDetail = new Find();
testDetail.enPassant(detailArray);

}

}

Output: Enpassant: kq

My intended output is: Enpassant: none

Why am i getting kq, and what can i do to correct my mistake?

Answer 1

//Find.java
public class Find {
    public void enPassant(char[] array) {
        int count = 0;
        for (int i = 0; i < array.length; ++i) {
            if (array[i] == 'e') {
                count = i;
            } else {
                count += 0;
            }
        }

        if (count > 0) {
            System.out.println("Enpassant: " + array[count] + array[count + 1]);
        }

        if (count == 0) {
            System.out.println("Enpassant: none");
        }
    }

}
