Doubt about Fibonacci series

Question

Why didn’t my code print the first 300 numbers in the Fibonacci series and start finding negative numbers? What’s the problem with this code? Because he only goes up to 92?

 final int ARRAY_SIZE = 300; 
    long[] fib = new long[ARRAY_SIZE];


    fib[0] = 0; fib[1] = 1; 
    int n = 2; 
    boolean tooBig = false; 


    while(!tooBig){  
      fib[n] = fib[n-1]+fib[n-2]; //formula!
      if(fib[n]<fib[n-1]) {
    tooBig=true;
  }else
    n++;
}


println("The first "+n+" Fibonacci numbers are:");
//Experiment: Try changing "i<n" to "i<=n".
for(int i=0; i<=n; i++){
  println("Fib: " + i + " " + fib[i]+ " ");
  }
