# cannot convert from Class<capture#1-of ?> to Class<?>[]

What does it [mean](https://yourviews.mindstick.com/view/80768/what-does-real-minority-mean), the following [error message](https://www.mindstick.com/forum/23174/error-message-the-page-you-are-requesting-cannot-be-served-because-of-the-extension-configuration):

```
Type mismatch: cannot convert from Class<capture#1-of ?> to Class<?>[]
```

The [code](https://yourviews.mindstick.com/view/85458/alan-turing-the-mastermind-behind-cracking-the-enigma-code-during-world-war-ii) is following:

```
            Class<?>[] encoderClass;
            Class<?>[] encoderClasses = new Class<?>[] {
                Encoder1.class,
                Encoder2.class,
                Encoder3.class
            };

            for(int i=0; i<encoderClasses.length; ++i) {
                encoderClass = encoderClasses[i]; // <------ error is here
            }
```

You're attempting to assign a single class element to a class array (different types as per the [error](https://yourviews.mindstick.com/view/88527/fixing-quickbooks-error-4120-reinstalling-vs-repairing) [message](https://www.mindstick.com/forum/12802/show-confirmation-message-yes-or-no-in-asp-dot-net)). Instead, assign each individual element in the for loop

```
encoderClass[i] = encoderClasses[i];
```

ensuring that the array is initialized to avoid NPE in the assignment

```
Class<?>[] encoderClass = new Class<?>[3];
```

For simplicity you could replace the entire loop with

```
encoderClass = Arrays.copyOf(encoderClasses,  encoderClasses.length);
```
