Fibonacci Series
This Program generates Fibonnaci Series for a given number of times.
Output: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55
[sourcecode language='java']
public class FibonnaciSeries {
/*
* Generates the Fibonnaci Series
*/
public void generateSeries(int num) {
int f1, f2 = 0, f3 = 1;
System.out.println(”fib(0) = ” + f2);
for (int i = 1; i <= num; i++) {
System.out.println("fib(" + i + ") = " + f3);
f1 = f2;
f2 = f3;
f3 = f1 + f2;
}
}
public static void main(String[] args) {
System.out.println("*****Fibonnaci Series*****");
FibonnaciSeries fb = new FibonnaciSeries();
fb.generateSeries(10);
}
}

Highest Prime Number
Given a number this program generates the highest prime number.
Output: If the input is 25, the highest prime number close to 25 is 23. It prints 23.
[sourcecode language='java']
public class PrimeNumber {
/*
* Given a number, finds the highest prime number.
*/
public static int highestPrime(int n) {
int value = 1;
for (int i = 2; i <= n; i++) {
// System.out.println("n: " + n + " i: " + i + " mod: " + n%i);
if (i == n) {
value = n;
break;
}
if (n % i == 0) {
n--;
}
}
return value;
}
public static void main(String[] args) {
int value = highestPrime(25);
System.out.println("Prime:" + value);
}
}

Triangle Printing
Given a number, this program prints the numbers in the right angle manner.
Output:
1
2 3
4 5 6
7 8 9 10
11 12 13 14
[sourcecode language='java']
public class TrianglePrinting {
/*
* Prints the numbers in the right angle manner.
*/
public static void trianglePrinting(int n) {
int counter = 0, i = 1;
while (i <= n) {
counter++;
for (int j = 0; j < counter; j++) {
if (i > n)
break;
System.out.print(i + ” “);
i++;
}
System.out.println();
}
}
public static void main(String[] args) {

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
1
121
1231
12341
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..

see you mean to input a String
you need to input it.
//suppose s is String
int hn=0;
int c=0;
int i,j;
for(i=0;i<s.length();i++)
{
//remaining part
char ch=s.charAt(i);
//search for next now
for(j=0;j<s.length();j++)
{
char chr=s.charAt(j);
if(ch==chr) c++;
}
c–;
if(h<c){ h=c; //you have to take an
//int variable and v=i; as
//i forgot to take v in start.
}
}
System.out.println(s.charAt(v)); //remember v
System.out.println(h);

Hey guys I am from India and I guarantee you that this Fibonacci number series program will work:-
import java.io.*;
class fibonacci
{
public static void main(String args[])throws IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
int num,ans1=1,ans2=0,ans3;
System.out.println(”Enter number”);
num=Integer.parseInt(br.readLine());
num=num-2;
System.out.print(ans2);
System.out.print(” “);
System.out.print(ans1);
System.out.print(” “);
while(num!=0)
{
ans3=ans1+ans2;
System.out.print(ans3);
System.out.print(” “);
ans2=ans1;
ans1=ans3;
num=num-1;
}
}
}
hi friendz
can anyone give me the code for the prog:
to accept a string from the user and change the beginning letter of every word with a CAPITAL letter.
/* 1
1 2 1
1 2 3 1
1 2 3 4 1
*/
import javax.swing.*;
public class OneAngle {
public static void main(String[] args) {
String input = JOptionPane.showInputDialog(”Enter num?”);
int n = Integer.parseInt(input);
int count = 0;
for(int i = 1; i <= n; i++) {
count++;
for(int j = 1; j 1) System.out.print(1);
System.out.println();
}
}
}
can you help me how to figure out this java problem.. here is the output..
