Null is a term used in programming to represent the absence of a value or a non-existent value. It is often used to indicate that a variable or an object has no assigned value. In computer science, null is typically represented as a special value that is assigned to a variable or a pointer. When a null value is encountered in a program, it can trigger errors or unexpected behavior, so it is important to handle null values appropriately in software development翻译
