Print First n numbers in Fibonacci Series

by

Objective: Write a program to print first n numbers in Fibonacci series.

Fibonacci number: First two Fibonacci numbers are defined as 0 and 1 and every number after the first two is the sum of the two preceding ones

Fibonacci Sequence- 0 1 1 2 3 5 8 13 21 34 55 89 ……..

Code:


public class FibonacciSeries {
public static void printFibonacci(int n){
int one = 0;
int two = 1;
System.out.println("First " + n + " elements in fibonacci series are: ");
for (int i = 0; i <n ; i++) {
System.out.print(one + " ");
int temp = one + two;
one = two;
two = temp;
}
}
public static void main(String[] args) {
int n = 10;
printFibonacci(n);
}
}
