Java program for fibonacci series

Question

import java.util.Scanner;
public class Program {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
int a = 0;
int b = 1;
int i=1;
System.out.println(a);
System.out.println(b);
if(i<x){
int sum = a+b;
System.out.println(sum);
a=b;
b=sum;
i++;
}
}
}

I m not getting required output while using if loop.
But when I used for loop I got it. Can anyone tell me what's wrong in this if loop

Answer 1

for loops continue to run through the set parameters, acting upon the statement each iteration.

An if statement is assessed once
if (i < x) -> true
sum = a + b -> 0+1 -> 1

Answer 6

"if" is not a loop
it executes only one time

"while" and "for" are loops.
It iterates through the code block till a certain condition is not satisfied.
If no terminating conditions are described, the loop runs infinitely.
