    import java.util.Scanner;
    public class series
    {
    public static void main (String[]args){
    Scanner in = new Scanner (System.in);
    System.out.println(“Type in the number of terms”);
    int n = in.nextInt();

    if (n == 1)
    {
    System.out.println(“1″);
    return;
    }

    if (n == 2)
    {
    System.out.println(“1 1″);
    return;
    }

    int res = 1 ;
    int fnum = 1;

    System.out.print(“1 1 “);

    for (int i = 1 ; i<=n ; i++){
    int temp = res;
    res = fnum;
    fnum = res + temp;
    System.out.print(fnum + " ");
    }
    }
    }

    How do i convert this into buffered reader ??

    Try this way also:
    class FibbbSeriesssprevious3
    {
    public void input(int n)
    {
    System.out.print(0+”,”+1);
    int a=0,i=1,p=0;
    while(i<n)
    {
    a=a+i+p;
    if(a<=n)
    System.out.print(","+a);
    i=i+a+p;
    if(i<=n)
    System.out.print(","+i);
    p=i+p;
    if(p<=n)
    System.out.print(","+p);
    }}}

    Sorry I posted a wrong program,
    this is the correct one:
    class FibbbSeriesssprevious2
    {
    public void input(int n)
    {
    int a=0,i=1;
    while(a<n)
    {
    if(a<=n)
    System.out.print(a+",");
    a=a+i;
    if(i<=n)
    System.out.print(i+",");
    i=i+a;
    }}}

    public class Fibonacci{
    public static void main(String args[]){
    int a=0;
    int b=1;
    int temp=0;
    for(int i=1; i<=15; i++){
    System.out.println(temp+"="+"fibonacci");
    a=b;
    b=temp;
    temp=a+b;
    }
    }
    }

    help me write a program dat will generate this fibonacci series 1,1,2,3,5,8,13

    public class Fibonacci
    {
    public static void main(String args[])
    {
    int i=0;
    int j=1;
    int num=0;

    for(int a=0; a<=7; a++)
    {
    System.out.print(num+" ");
    i=j;
    j=num;
    num=i+j;
    }
    }

    class One

    public static void main(String args[])
    {
    int [] num={12,25,47,85,45,58,56,55,89,81,2,78};
    Arrays.sort(num);
    for(int k[].num);
    System.out.println(k);
    }
    }

    this program is used to sort elements.

    Here’s a simplified version. Cheers

    import java.util.*;
    class fib3
    {
    public static void main(String[] args)
    {
    System.out.println(“Enter fibonacci number: “);
    Scanner scan = new Scanner(System.in);
    int input = scan.nextInt();
    int fnum = 0, snum = 1, subsequent;

    for(int i = 0; i<input; i++)
    {
    System.out.println(fnum);
    subsequent = fnum + snum;
    fnum = snum;
    snum = subsequent;
    }
    }
    }
