please send me the java program of “prime number of Fibonacci series”
let us take e.g.
0, 1,1,2,3,5,8,13,………..
den prime number series will be- 3,5,13…………
amazing coding sir thanx
please send me th java programe “1 3, 2 4. 5 7, 6 8, 9 11, 10 12;”
sir, i want simple logic of prime number programs
what is fibonacci series
hi, i want a logic program like

please send array using java
wowwwwwwwwwwwwwwww
FibonacciSeries class would never compile , because of the blunders in the code
Hope u can the see double ‘n’ s used while creating a new instance of the class,
It becomes a minimal etiquette to check the code (run it in u r machine )
as many of the newbie’s may take as reference and copy the same code and try to run it
hope u take this in the +ve manner
This is the output generated by the Fibonacci Series Program.
It is 100% correct. Let me know what is the output u r getting.
Let’s consider v1= 5, v2 = 10, then v3 = 15 (i.e v1 + v2)
v4 = 25 (i.e. v3 + v4) there on…..
Fibonacci Series
*****Fibonacci Series*****
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
Copy the same code that you have pasted ,u will get
FibonnaciSeries cannot be resolved
to a type
Copy the same code that you have pasted ,u will get
FibonnaciSeries cannot be resolved to a type error
because of the spelling mistakes as u r class name is
FibonacciSeries and u r instantiating a new object with
FibonnaciSeries fb = new FibonnaciSeries(); (which contains single n and double c’s)
So i wondered did u ever run in u r machine
Thanks for the correction. The program is updated.
the second program will also be modified to be divided by 3 because if you take 21 as an example if you divide it by 2 it will say its prime number thou its not.. its divided by 3 .. I think we also need to add a if dividing the number with three..

Hi Shweta,
Ans to Q39:
The best way is to use String.split().this returns array of strings(words in statement).Pick every word or index in array and modify first char using char(0) and toUppercase and join all array elements again. Hope that makes sense
Q 22. Using switch case perform array operation
A. sorting of array no
B. searching a particular no (taken as an input)
C. Addition of total element in array.
Q.23. Write a program that accepts a shopping list of five items from the command line and stores them in a vector.
Q.24. Write a program, which will read a string and rewrite it in the alphabetical order. For example, the word STRING should be written as GNIRST
Q 25. Write a program, which will take three strings from the command line and display the number of characters in each string.
Q.26. Write a program to find out prime no from 1 to 100
Q.27. Write a program, which will read a text and count all occurrences of a particular letter.
Q.28. Write a program to produce the following form.
1
0 1
1 0 1
0 1 0 1
1 0 1 0 1 1
2 2
3 3 3
4 4 4 4
5 5 5 5 5 $ $ $ $ $
$ $ $ $
$ $ $
$ $
$
Q.29. Write a utility class to sort the employees according to their names.
Q.30. Write a program to calculate harmonic value. e.g 1+1/2+1/3……1/n
Q.31. Admission to a professional course is subject to the following conditions
a. Marks in mathematics >=60
b. Marks in physics >=50
c. Marks in chemistry >=40
d. Total in all three subjects >=120
OR
Total in mathematics and physics >=150
Given the marks in the three subjects, write a program to process the application to list eligible candidates.
Q.32. Write a class Student; store it in the package stud. Write a class Batch with information about subject, faculty, and timing. Store it in the package bat. Use the class Batch to set information in the Student class.
Q.33 Write a program to display Fibonacci series.e.g.. 1 1 2 3 5 8 13 21……n.
Q 22. Using switch case perform array operation
A. sorting of array no
B. searching a particular no (taken as an input)

/**
* Description: By definition, the first two Fibonacci numbers are 0 and 1, and
* each remaining number is the sum of the previous two. Some sources omit the
* initial 0, instead beginning the sequence with two 1s.
*
* In mathematical terms, the sequence Fn of Fibonacci numbers is defined by the
* recurrence relation Fn = Fn-1 + Fn-2 like F0= 0 and F1 = 1
*
* F-n = (-1)power(n+1) * Fn
*
* Fibonacci Series: … -8, -5, -3, 2, -1, 1, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34,
* 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765
