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
