Introduction
This question is a duplicate of a previously asked question. The question is about a NullPointerException that is thrown when a string is passed. This type of exception is thrown when a program attempts to use an object reference that has not been initialized. In this case, the string that is being passed is not initialized and thus the exception is thrown. This question will provide an explanation of what a NullPointerException is and how to resolve it.
Solution
The most likely cause of a NullPointerException when passing a string is that the string is null. To fix this, make sure that the string is not null before passing it. For example, you can check if the string is null before passing it:
if (string != null) {
// pass the string
}
