Mis on deklaratsioonide eesmärk, kasutades võtmesõnu 'const' ja 'val' Kotlinis?

In Kotlin, the keywords const and val are used to declare immutable values, but with different characteristics:

• const — are compile-time constants. They must be primitive types or strings and are declared at the object or file level. The value of const cannot be changed and is known during compilation.

• val — are runtime immutable variables. The value is assigned once during initialization and cannot be changed, but can be computed during execution.

Example:

const val MAX_COUNT = 100 // compile-time constant
val currentTime = System.currentTimeMillis() // immutable value at runtime
