Write a program to display the first N Fibonacci numbers, and also find and display their sum. The value of N has to be input by the user.

**Program:**

```
import java.io.*;
class Fibonacci{
public static void main(String args[])
throws IOException{
InputStreamReader in = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(in);
System.out.print("N = ");
int n = Integer.parseInt(br.readLine());
long sum = 0;
int a = 0;
int b = 1;
System.out.print("Fibonacci Series: ");
for(int i = 1; i <= n; i++){
long t = fibo(i);
sum += t;
System.out.print(t + "\t");
}
System.out.println("\nSeries sum = " + sum);
}
public static long fibo(int n){
if(n == 1)
return 0L;
else if(n == 2)
return 1L;
else
return fibo(n - 1) + fibo(n - 2);
}
}
```
