logic For Fibonacci
fib(0) = 0
fib(1) = 1
fib(2) = 1
fib(3) = 2
fib(4) = 3
fib(5) = 5
fib(6) = 8
fib(7) = 13
fib(8) = 21
fib(9) = 34
fib(10) = 55


import java.io.*;
class Fibonacci {

 public static void main(String args[]) {
 System.out.println("How many numbers of the sequence would you like?");
    InputStreamReader sr = new InputStreamReader(System.in);
    BufferedReader br    = new BufferedReader(sr);
 try {
      String input = br.readLine();
      int n = Integer.valueOf(input).intValue();
      fibonacci(n);
    } catch (NumberFormatException e){
      System.out.println("That is no integer. Please enter an integer value only");
    } catch (IOException e) {
      System.out.println("I did not recieve an input");
    }
  }

public static void fibonacci(int n){
    int a=0,b=1;

    for (int i=0;i<n;i++){
      System.out.println(a);
