FibonacciFor.java

/* Program for Printing first N terms of Fibonacci series using for loop (without taking input from user)
* Code by Vivek R (vividvilla) - Contact me at - http://vivek.techiestuffs.com

public class FibonacciFor {

  public static void main(String[] args) 
  {
    int n=10,first=0,second=1,next,i;
    System.out.println("Printing first "+n+" numbers in Fibonacci Series \n");
    for(i=0;i<n;i++)
    {
      if(i<=1)
      next=i;
      else
      {
        next = first + second;
        first = second;
        second = next;
      }
    System.out.print(next + "\t");
    }
  }
}

fibonacci(N) = Nth term in fibonacci series
fibonacci(N) = fibonacci(N - 1) + fibonacci(N - 2);
whereas, fibonacci(0) = 0 and fibonacci(1) = 1

I am excited to begin the programming journey

int f_n, f_n_1, f_n_2, n;
int i =0;

Scanner input = new Scanner (System.in);
System.out.print("mengambil fibonacci ke - ");
n = input.nextInt();

 f_n_2 = 1;
 f_n_1 = 0;
 f_n = 0;
 
for(i = 0; i <= n; i++){
 System.out.println("nilai ke - " + (i+1) + " adalah "+ f_n);
    f_n = f_n_1 + f_n_2;
    f_n_2 = f_n_1;
    f_n_1 = f_n;
       
}
