im trying to make a program where the user enters a number and the console is that fibonacci number. im having trouble figuring out why the like fibbonaci fib = new fibonacci is stopping my program. when the computor reads that line, the code juts stops to run.
Edit: Thanks so much for the answers guys, but im still having trouble understanding. could somone please rewrite the code so that the error is fixed? thanks!
Edit: i figured it out, thanks for all the help!
import java.util.Scanner;
public class fibonacci {
Scanner fnumber = new Scanner (System.in);
int input = fnumber.nextInt();
int f1 = 1;
int f2 = 1;
int answer = f1 + f2;
public int fibonacci( int input) {
for(int f2 = 1; f2<input; f2++ ) {
int answer = f1 + f2;
f1 = f2;
f2 = f2 + 1;
}
return answer;
}
public static void main(String args[]){
System.out.println("please enter a number");
Scanner fnumber = new Scanner (System.in);
int input = fnumber.nextInt();
System.out.println("The " + input + "th number of the fibonacci sequence is " + fib.fibonacci(input));
}
}
You have to create an object of your class. then call the method using object in main method (static).
fibonacci fib = new fibonacci();
fib.fibonacci(input);
instantiate the fibonacci class in your main.
fibonacci f = new fibonacci ();
f.fibonacci(input);
Also, your class (and file) should be named Fibonacci. Classes name always have a capital first letter.
