import java.util.*;
public class Fibonacci
{
public static void main(String args[ ])
{
Scanner s=new Scanner(System.in);
System.out.print("Enter no. of terms:");
int n=s.nextInt();
int i, k1=0,k2=1,sum=0;
for(i=1;i<=n;i++)
{
System.out.print(k1+"+");
sum=k1+k2;
k1=k2;
k2=sum;
}
System.out.print("\n Sum is "+ sum);
}
}
Output: Enter no. of terms: ...
0+1+1+2+3+5.....+n
Sum is .....

Yes, u r right
I will try again and edit the answer.
ok
See, it can be corrected by replacing the last print line by this: System.out.print("Sum is "+sum-1);
Hope it works...
Try and tell. :-)
i tried the same ( sum-1) btw in the o/p its printing the the value of sum minus 1. suppose sum= 4, so in the o/p its giving 4 - 1
its shouldn't be displayed in that format.
so try using a variable x=sum-1; and then print itas "Sum is "+ x
okay ..let me try

Answer:public class fibonacci_series
{
public static void main(int n)
{
int a=0;
int b=1;
int s=0;
int c=0;
int i;
s=s+a+b;
System.out.print("The fibonacci series = "+a+","+b+",");
for(i=3;i<=n;i++)
{
c=a+b;
System.out.print(c+",");
a=b;
b=c;
s=s+c;
}
System.out.println("upto "+n+" terms completed");
System.out.println("\nThe sum of the fibonacci series upto "+n+" terms = "+s);
}
}
