Help with Lucas series

[gray tusk]

So I have this code which prints the lucas series.

Lucas series is a series which starts from 2 and 1 and the following numbers are the sum of the previous 2 number like

        2
        1

2 +1 = 3
3 +1 = 4
4 +3 = 7
and so on.

import java.util.*;
public class Main
{
    public static void main(String[] args) {
        int a=2,b=1,c,i;
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter the length of lucas series:");
        int len=sc.nextInt();
        for(i=1;i<=len;i++){
            c=a+b;
            System.out.print(c+" ");
            a=b;
            b=c;
        }
    }
}

So the problem is if I for example say input 10 for the scanner input. Then it starts from 3, 4, 7, etc. So how do I get the first 2 and 1? I need it to print all 10 starting from 2 and 1.
So that is 2,1,3,4,7....

is it possible to print the first 2 numbers with the loop and not just doing prntln(a) and println(b) ?

Possible sure, but not necessarily satisfying

Just do

if(i == 1) {
 a = 2;
 c = a;
} else if(i == 2) {
  b = a;
  a = 1;
  c = a;
}

I see, I will just simply print them then, it makes the code unnecessarily big..

thank you
