Kotlin: String template expressions

By using template expression, you can evaluate the expression in a string. Template expression starts with $ symbol followed by a name.

Ex

var a = 10

println("Value of a is : $a")

Arbitrary expression are enclosed in curly braces

var str = "Hello World"

println("$str length is ${str.length}")

Expression.kt

fun main(args: Array<String>) {
 var a = 10
 var str = "Hello World"

 println("Value of a is : $a")
 println("$str length is ${str.length}")
}

Output

Value of a is : 10
Hello World length is 11
