Cannot invoke "String.equalsIgnoreCase(String)" because "code" is null

I apologize for the inconvenience. It seems that the variable "code" is currently null, which is causing the error when trying to invoke the `equalsIgnoreCase()` method on it.
To avoid this error, you should check if the "code" variable is null before invoking any methods on it. You can use an if statement or a null check to ensure that the variable has a value before performing any operations on it.
Here's an example of how you can modify your code to handle this situation:
```java
if (code != null && code.equalsIgnoreCase("yourString")) {
// Perform the desired operation
}
```
By checking if the "code" variable is null before invoking the `equalsIgnoreCase()` method, you can prevent the error from occurring.
