It seems like you're getting a `NoSuchElementException`. This exception is thrown by the `Scanner` class when you're trying to read an input but there is no input available.

In your case, it's happening at the `getData` method of the `CIRCLE` class, when you're trying to read a double.

Here's a step-by-step guide to fix this:

1. Check if you're calling `Scanner.nextDouble()` without actually having a double to read. You might be calling this method more times than the number of doubles in your input.

2. Make sure you're providing the correct input to your program. If your program is expecting a double, you should provide a double.

3. You can also add a check before calling `nextDouble()` to see if there is a double available to read. You can do this using the `Scanner.hasNextDouble()` method. This method returns true if the next token in the input can be interpreted as a double.

Here's how you can do it:

```java
if(scanner.hasNextDouble()) {
double num = scanner.nextDouble();
// rest of your code
} else {
System.out.println("No double available to read");
}
```

This will prevent `NoSuchElementException` from being thrown.
