The null literal can be assigned to any Object reference in Java, and is usually used to indicate the absence of something. The main use of it is to indicate that a reference has yet to be instantiated. It can also be used as a return type for things like Collections to indicate that the object you're looking for doesn't exist in that particular Collection.

What keyword is used to declare a named constant?
Constant in Java refers to a fixed value that doesn’t change during the execution of a program. The value of constants appears right in a program. It is also known as Literals. We use the constants to create values that assign to variables. Constants can make our program easy to read and understood by others. Java does not directly support the constant. To define a variable as a constant, We use the “Static” and “Final” Keywords before declaring a variable. Hope this helps. Thank you
