In this tutorial, you will learn how to display the Fibonacci series in Java using the “for loop.” The Fibonacci series is a series of integers where the next number is the sum of the previous two numbers. The first 2 number of the series are 0 and 1.
The Fibonacci series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, …
Display Fibonacci series in Java using ‘for loop’
In the example below, we will display the series up to the number 100.
public class Main { public static void main(String[] args) { int numberOfTerms = 20; int Term1 = 0; int Term2 = 1; System.out.print("First 20 terms: "); for (int i = 1; i <= numberOfTerms; ++i) { System.out.print(Term1 + ", "); int sum = Term1 + Term2; Term1 = Term2; Term2 = sum; } } }
Output
First 20 terms: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181,
