Java for loop calculate fibonacci sequence

Introduction

This program prints out the first 20 numbers in the Fibonacci sequence.

Each number is formed by adding together the previous two terms in the sequence, starting with the terms 1 and 1. 

public class Main {
  public static void main(String[] args) {
    int n0 = 1, n1 = 1, n2; // Initialize variables
    System.out.print(n0 + " " + // Print first and second terms
        n1 + " "); // of the series

    for (int i = 0; i < 18; i++) { // Loop for the next 18 terms
      n2 = n1 + n0; // Next term is sum of previous two
      System.out.print(n2 + " "); // Print it out
      n0 = n1; // First previous becomes 2nd previous
      n1 = n2; // And current number becomes previous
    }//w  ww  . j a  v a 2  s  . c o  m
    System.out.println(); // Terminate the line
  }
}
