Question: I am very new to Java, sorry if the question is too simple. I am trying to evaluate whether an array is part of the fibonacci sequence. I do not know how to return "true" value when the whole "for" loop does not break. Any ideas? Thank you in advance! This is what I have for now:

```
public boolean checkFibb(ArrayList<Integer> array1) {
    int i;
    int fibb;

    if (array1.size() < 3) {
        System.out.println("Your array is too short!");
    } else {
        for (i = 0; i <= array1.size() - 2; i++) {
            fibb = array1.get(i + 2) - (array1.get(i + 1) + array1.get(i));

            if (fibb != 0) {
                System.out.println("Elements are not part of the Fibonacci sequence.");
                break;
            } else {
                System.out.println("Elements are part of the Fibonacci sequence.");
            }
        }
    }

    return true;
}

```

Answer: 
You always return `true` from the method. You should do something as follows:

```
public boolean checkFibb(ArrayList<Integer> array1) {
   int i;
   int fibb;
   boolean isFibb = true;

   if (array1.size() < 3) {
       System.out.println("Your array is too short!");
       isFibb = false;
   } else {
       for (i = 0; i <= array1.size() - 2; i++) {
           fibb = array1.get(i + 2) - (array1.get(i + 1) + array1.get(i));

           if (fibb != 0) {
                System.out.println("Elements are not part of the Fibonacci sequence.");
                isFibb = false;
                break;
           } else {
                System.out.println("Elements are part of the Fibonacci sequence."); 
           }
       }
   }
   return isFibb;
}

```
What you're doing in your code is you're breaking the current iteration of the loop when you detect that the elements aren't part of a fibonacci sequence. `break` only stops the current iteration of the loop that you are in. What you want to do is `return false` from the function at this point. When you detect that the array is indeed a fibonacci sequence you would want to `return true` at this point.

If you array is too short, it cannot be a fibonacci sequence thus you would `return false` at this point. 

```
public boolean checkFibb(ArrayList<Integer> array1) {
int i;
int fibb;

if (array1.size() < 3) {
    System.out.println("Your array is too short!");
    return false;
} else {
    for (i = 0; i <= array1.size() - 2; i++) {
        fibb = array1.get(i + 2) - (array1.get(i + 1) + array1.get(i));

        if (fibb != 0) {
            System.out.println("Elements are not part of the Fibonacci sequence.");
            return false;
        } else {
            System.out.println("Elements are part of the Fibonacci sequence.");
            return true;
        }
    }
}

```
