Generate Fibonacci series using Java For/While loop.

Program-

import java.util.*;

public class Fibonacci {

 public static void main(String[] args){

 Scanner sc = new Scanner(System.in);

 System.out.println("Enter a number : ");

 int n =sc.nextInt();

if(n==1){

 System.out.println("0");

 }

 else if(n==2){

 System.out.println("0 1");

 }

 else if(n>2){

 int a=0,b=1;

 System.out.print("0 1 ");

 for(int i=3;i<=n;i++){

 int temp = a+b;

 System.out.print(temp+" ");

 a=b;

 b=temp;

 }

 }

 else{

 System.out.println("Invalid input");

}

 }

}
