package sample;
import java.util.Scanner;
public class fibonacci {
public static void main(String[]args){
Scanner in=new Scanner (System.in);
int num,c,next=0,first=0,second=1;
System.out.print("Enter number: ");
num=in.nextInt();
System.out.print("Fibonacci Series: ");
for(c=0;c<num;c++){
if(c<=1)
next = c;
else{
next = first + second;
first = second;
second = next;
}
System.out.print(" "+next);
}
}
}

Output:
Enter number: 9
Fibonacci Series: 0 1 1 2 3 5 8 13 21

This is not a Java forum.
Also, you should try to think about the problem.
It works on the fact that you can calculate the next Fibonacci number knowing only the previous two.
in C++:

#include <iostream>
using namespace std;
int main()
{
int num, c, next = 0, first = 0, second = 1;
cout << "Enter number: ";
cin >> num;
cout << "Fibonacci Series: ";
for (c = 0; c < num; c++)
{
if ( c <= 1 )
next = c;
else
{
next = first + second;
first = second;
second = next;
}
cout << " " << next;
}
}
