fibonicci code in java code example

Example 1: java fibonacci series code

public class Fibonacci {

    public static void main(String[] args) {

        int n = 10, t1 = 0, t2 = 1;
        System.out.print("First " + n + " terms: ");

        for (int i = 1; i <= n; ++i)
        {
            System.out.print(t1 + " + ");

            int sum = t1 + t2;
            t1 = t2;
            t2 = sum;
        }
    }
}

Example 2: fibonacci java

import info1.*;

public class FibonacciDemo1{

  public static void main(String[] args){

    System.out.print("Geben Sie ein Zahl an: ");

    int a = Console.in.readInt();

    System.out.println("fib("+a+") = " + fibonacci(a));

  }

  private static int fibonacci(int a){

    if (a==1||a==2) return 1;

    else return fibonacci(a-1)+fibonacci(a-2);

  }

}
