A constant and variable are variations of data types. int a; is a variable and its value can be changed by the program as the program runs. const int b; is a constant with a fixed value and will have its value set and may not be changed by the program as as the program runs. All data types may be declared as a constant. Variable Value Can Be Changed By You In Programme.
Macros are processed at preprocessing time where as constant variables are processed at complie time. Macros doesnot have any scope but constant variables has scope. Macros doesnot have the type checking where as constant variables have type checking.
Variables are items, which change their values during the execution of a program. Constants do not change the value during the execution of a program.
A constant variable cannot have its value changed at program run time.
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

A constant is a fixed value that does not change during a calculation or program. It is assigned a specific value at the beginning and remains constant throughout. A value, on the other hand, refers to the numerical representation of a variable, result, or data point within a program or calculation.
A number value that does not change is called a "constant." In mathematics and programming, a constant represents a fixed value that remains the same throughout a calculation or a program's execution, as opposed to a variable, which can change. Examples of constants include numbers like π (pi) or specific values defined in a mathematical context.
An aggregate constant is a nonscalar constant which value never change or are not changed during execution of the program.
A named constant is a value that does not change during the execution of a program. It is assigned a name or identifier that represents the value, making the code more readable and easier to maintain. Named constants are typically declared at the beginning of a program and are used when a value needs to remain constant throughout the program's execution.
It means a value that isn't a variable.For example, "X" is a variable, since its value can vary.Now, the number "33" is a constant, because its value is constant, or unchanging.(If 33 were to become 34, it wouldn't be 33 anymore.)(If x's value were to change from 5 to 8, it's still x, but its value varied.)
A constant is a name that represents a value that cannot be changed during the program's execution. Constants are typically assigned a value when declared and cannot be reassigned or modified while the program is running.

A constant is a variable whose value does not change during the program's execution. Constants are usually written in uppercase letters with underscores separating words and their value remains fixed throughout the program.
