Hey, /sci/. I'm working on learning Java right now and I'm trying to make a Fibonacci sequence generator. What am I doing wrong?

class fibonacci{
public static void main(String args[]) {
int num1 = 0;
int num2 = 1;
int num3 = num1 + num2;
int n = 0;
while(n < 10){
System.out.println(num3);
num1 = num2;
num2 = num3;
n++;
}
}
}

All I get is a bunch of 1s. I just started learning today, so be nice, please.

Why would the value of num3 change? That's what you're outputting.

So would I throw another
num3 = num1 + num2;
inside of the while?

Yup... I knew it was something obvious. Thanks, anon. :)

Yes, but where you put it is important.

num3 = num1 + num2 needs to be inside your loop

The way you have it now, your loop isn't doing anything. There are also more efficient ways to generate Fibonacci numbers, but stick to the simplest for now.
