Answer 1

to give a totally recursive definition:

If you're interested in large fib numbers this is not the best approach to take, I would advise looking into dynamic programming. I have rigged up an example for you here:

Note how much faster the dynamic approach is compared to the recursive.

Answer 2

/* Fibonacci Series */

import java.io.*;

class Fibonacci
{
public static void main(String args[])
{
String str;
int no,f1,f2,f3;
f2=0;
f3=1;

try{
System.out.print("Enter number to generate it's Fibonacci Series : ");
System.out.flush();
BufferedReader obj = new BufferedReader(new InputStreamReader(System.in));
str=obj.readLine();
no=Integer.parseInt(str);

System.out.print(f3+" ");
System.out.flush();
while(no>1)
{
f1=f2;
f2=f3;
f3=f1+f2;
System.out.print(f3+" ");
System.out.flush();
no=no-1;
}
}
catch(Exception e)
{}
}}
