“Getter and Setter di Kotlin” Kode Jawaban

getters dan setters Kotlin

Getters and setters are auto-generated in Kotlin. If you write:

val isEmpty: Boolean
It is equal to the following Java code:

private final Boolean isEmpty;

public Boolean isEmpty() {
    return isEmpty;
}
In your case the private access modifier is redundant - isEmpty is private by default and can be accessed only by a getter. When you try to get your object's isEmpty property you call the get method in real. For more understanding of getters/setters in Kotlin: the two code samples below are equal:

var someProperty: String = "defaultValue"
and

var someProperty: String = "defaultValue"
    get() = field
    set(value) { field = value }
Also I want to point out that this in a getter is not your property - it's the class instance. If you want to get access to the field's value in a getter or setter you can use the reserved word field for it:

val isEmpty: Boolean
  get() = field
If you only want to have a get method in public access - you can write this code:

var isEmpty: Boolean
    private set 
due to the private modifier near the set accessor you can set this value only in methods inside your object.
