Describe three ways in which a named constant differs from a variable.
What will be an ideal response?
In its declaration statement, the data type of a named constant is preceded by the keyword final.A named constant can be assigned a value only once, and then it cannot be changed later in the program. Usually you initialize a named constant when you declare it; if you do not initialize the constant at declaration, it is known as a blank final, and you can assign a value later. Either way, you must assign a value to a constant before it is used.Named constants conventionally are given identifiers using all uppercase letters, using underscores as needed to separate words.
