Variable might not have been initialized

Question

Why do I get an error like this: "result" might not have been initialized.

import java.util.Scanner;

public class gyak {
public static void main(String[] args){
Scanner scanner = new Scanner(System.in);
int a = scanner.nextInt();
int result;
for (int i=a-1;i>=1;i--){
result= a*i;

}
System.out.println(result);

}
}
