kotlin constante

To define a constant in Kotlin, you can use the "val" keyword followed by the constant name, an equal sign "=", and the constant value. Here is an example:

val PI = 3.14159

In this example, the constant "PI" is assigned the value 3.14159. The "val" keyword is used to declare a read-only property, which means that once a value is assigned to the constant, it cannot be changed.

Constants in Kotlin are similar to variables, but with one important difference: their values cannot be modified once they are assigned. This ensures that the value of a constant remains constant throughout the program execution.

By using constants, you can assign meaningful names to values that will not change, making your code more readable and maintainable. Constants are often used to store values such as mathematical constants, configuration settings, or other fixed values that are used throughout the program.

To summarize, in Kotlin, you can define a constant using the "val" keyword followed by the constant name, an equal sign "=", and the constant value. Once a value is assigned to a constant, it cannot be changed. Constants are useful for storing values that remain constant throughout the program execution.
