The Concept Of Null In Java
null is a reserved word (keyword) in Java for literal values. It is a literal similar to the true and false. In Java, null is a keyword much like the other keywords public, static or final. It is just a value that shows that the object is referring to nothing. The invention of the word “null” originated to denote the absence of something. For example, the absence of the user, a resource, or anything.
