String Templates

String templates are used to insert a variable’s value into a string. String literals may contain template expressions, i.e. pieces of code that are evaluated and whose results are concatenated into the string.

A template expression starts with a dollar sign ($) and consists of either a simple name.

fun main(args: Array<String>)
{
    var x = 5
    val text = "Value is $x"
    println(text)    
}

Value is 5

Anything in the curly brackets starting with a $ sign will be evaluated and the result will be put in the string.

fun main(args: Array<String>)
{
    var x = 5
    var y = 6
    val sum = "Sum is ${x + y}"
    println(sum)    
}

Sum is 11

Kotlin String template with raw string

We have already seen how to use string template with escaped string. Now, we will see how to use string templates with raw string.

Like escaped string, string template in raw string  starts with $ sign.

fun main(args: Array<String>)<br />{<br />    val price = """<br />${'$'}200<br />"""<br />   print(price)    <br />}

$200
