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);
}

}
[/sourcecode]

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);
}

}
[/sourcecode]

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) {
trianglePrinting(14);
}

}
[/sourcecode]

    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…………

  9. nightfox Says: February 27th, 2009 at 8:48 pm

    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

  10. Chandra Says: February 28th, 2009 at 7:00 pm

    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

  11. nightfox Says: February 28th, 2009 at 8:42 pm

    Copy the same code that you have pasted ,u will get
    FibonnaciSeries cannot be resolved
    to a type

  12. nightfox Says: February 28th, 2009 at 8:47 pm

    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

  13. Moon Says: March 1st, 2009 at 10:38 am

    Thanks for the correction. The program is updated.

  14. Raja Says: April 29th, 2009 at 8:18 am

    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++)
    {

  29. saksham Says: September 14th, 2009 at 7:15 am

    //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);

    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

    * 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,
