BERIKUT SYNTACS JAVA-nya :

import javax.swing.JOptionPane;
 
 /*
    This program computes Fibonacci numbers using a recursive
    method.
  */
 public class Fibonacci
{ 
    public static void main(String[] args)
    { 
       String input = JOptionPane.showInputDialog("Enter n: ");
       int n = Integer.parseInt(input);
 
       for (int i = 1; i <= n; i++)
       {
          int f = fib(i);
          System.out.println("fib(" + i + ") = " + f);
       }
       System.exit(0);
      
    }
 
    /**
       Computes a Fibonacci number.
       @param n an integer
       @return the nth Fibonacci number
    */
    public static int fib(int n)
    { 
       if (n <= 2)
            return 1;
       else
            return fib(n - 1) + fib(n - 2);
    }
