NichtNullWerts

NichtNullWerts is a term that appears in certain programming contexts, particularly within the Java ecosystem, referring to a concept related to handling non-null values. The term itself is a compound of German words: "nicht" meaning "not" and "Null" meaning "null," followed by "Werts" which can be interpreted as "value." Therefore, "NichtNullWerts" essentially translates to "non-null value."

This concept is most commonly associated with annotations in Java, such as `@NonNull` or `@NotNull`. These annotations are used by developers to explicitly declare that a variable, parameter, or return value is expected to never be null. The primary purpose of these annotations is to improve code readability and to enable static analysis tools, such as compilers or specialized checkers, to detect potential NullPointerExceptions before the code is even run. By clearly marking where null values are not permitted, developers can create more robust and reliable software. The implementation and enforcement of these annotations can vary depending on the specific tools and frameworks being used.
