Fibonacci series in java 

//file name--> Fibonacci.java

import java.io.*;
class Fibonacci{
 public static void main(String args[])throws Exception
 {
  BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
  
  int p=0,c=1,n=p+c,num;
  
  System.out.println("Enter number of Series you want:");
  num=Integer.parseInt(br.readLine());
  
  for(int i=0;i < num-1;i++)
  {
   if(i==0)
    System.out.print(p);
    
   System.out.print("\t "+n); 
   n=c+p;
   p=c;
   c=n;
  }
 }
}

OUTPUT

javac Fibonacci.java

java Fibonacci
Enter number of Series you want:
