java fibonacci sequence 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);
}
}
Example 3: fibonacci sequence algorithm in java
public class Fibonacci_sequence {
static int fib(int n) {
if( n <= 0 ) {
return 0;
}else if( n == 1 ) {
return 1;
}else {
return ( fib( n - 1 )+ fib( n - 2 ));
}
}
public static void main(String[] args) {
int n = 9;
System.out.println(fib(n));
}
}
