In Kotlin whatever value you define here that determines the data types of the variable. Suppose (var myNumber =10),that automatically becomes integer value. Similarly, you can write the datatypes of the variable (var myString: String). In case of the mutable string, you can modify string at any point of time. Example of mutable & immutable string-<\/p>\n
fun main(args: Array<String>) {<\/p>\n
var myString: String\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\/\/ Mutable String
\nmyString = “Hello World”
\nmyString = “Another World”<\/p>\n
val myAnotherString = “My Constant String”\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \/\/\u00a0 Immutable String<\/p>\n
myAnotherString = “Arin”\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0……Error will be given in this line because Immutable String cannot be modified<\/p>\n

String Interpolation :-<\/strong><\/p>\n In Kotlin String interpolation process is little bit different from any other languages.Example-<\/p>\n fun main(arg: Array<String>) {<\/p>\n var rect = Rectangle()\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\/\/\u00a0 creating object of Rectangle class named rect print(” length = ${rect.length} and breadth = ${rect.breadth}. Area is ${rect.length * rect.breadth}”)<\/p>\n }<\/p>\n class Rectangle {<\/p>\n var length: Int = 0 }<\/p>\n Output :<\/strong><\/p>\n length = 5 and breadth = 3.
