Question

Why can't this programme display result:

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int a = scanner.nextInt();

for (int i=a-1;i<=1;i--){
int result= a*i;

}
System.out.println(result);

}
}

Answer 1

I think you should change
the bottom limit in your for cycle. Your limit is I <=1 which means the cycle won't stop - an infinite loop.
Maybe you mean I>=1.Also the result variable should be declared outside of the for loop.

Answer 2

You declared the variable result inside the for loop, so it can only be used there. To fix it, put int result before the for loop.

Answer 3

I'm not great at java, but I think you should do int result = new Int ();

Answer 4

thanks

Answer 5

But still if I change the above mentioned things, it says 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);

}
}

Answer 6

That wouldn't be good syntactically, I get the error when I try to print it out.

Answer 7

I had to set the starting value of result, now it works
