The let variables have the same execution phase as the var variables. The temporal dead zone starts from the block until the let variable declaration is processed. In other words, it is the location where you cannot access the let variables before they are defined. In this tutorial, you have learned about the differences between var and let
a := 10 b := "gopher". a will be declared as an int and initialized with value 10 where as b will be declared as a string and initialized with value gopher. Their equivalents using = would be. var a = 10 var b = "gopher". = is assignment operator. It is used the same way you would use it in any other language.
As refered in e.g here or in the Kotlin Coding Convention one should not override the getter if the result can change. class SampleArray (val size: Int) { val isEmpty get () = size == 0 // size is set at the beginning and does not change so this is ok } class SampleArray (var size: Int) { fun isEmpty () { return size == 0 } // size is set at
8. val declares an "immutable variable or rather symbol" that doesn't allow reassignment, right hand side of the assignment is evaluated immediately. var declares a "mutable variable" that allows reassignments later to the symbol, right hand side of the assignment is evaluated immediately just like val. def declares an "immutable symbol" that The difference between val and var is that val makes a variable immutable — like final in Java — and var makes a variable mutable. This simple rule (a) makes your code more like algebra and (b) helps get you started down the path to functional programming, where all fields are immutable.This is useful when you want to do something with a value before storing it. In Java you would put that code a constructor body. class Person (firstName: String, lastName: String) { // directly in val / var declarations val firstName = firstName.capitalize () val lastName = lastName // in init blocks val fullName: String init { fullName
Credit VaR can be calculated according to two approaches as follows: Approach 1 (preferred and should be your default): Credit VaR is the distance from the mean to the percentile of the forward distribution, at the desired confidence level (paraphrased from the PRMIA Handbook). This is nothing but the unexpected credit loss at the desired
On the other hand, the var variable holding struct can mutate itself. Similarly, the rule of let & var will apply to individual properties of the struct. Line 7 — Cannot assign to property| Оው удр еጿуδ | Գυйቨдриቶι гежጴз χըсоφαη |
