# Kotlin String Template Tutorial

In this section we will learn what the String Template is and how to use it in Kotlin.

## What is String Template in Kotlin?

Kotlin String Template is a way of creating a string value using the values of other variables or from the result of an expression.

Basically, when we want to mix in the value of a variable as part of a new string value, we can use the string template.

## Kotlin String Template Declaration Syntax:

``` line-numbers
“ ${variableName}”
`${}`: in order to mix in the value of a variable or an expression into the process of creating a string value, we use this symbol within a pair of double quotation and then within the curly braces we put the name of a variable or the expression we want to take its value and make it as part of the string value we’re creating.
```

Note that before or after the ${} we can put other string values as well.

Also if we only want to mix in the value of a variable into the string, we can remove the `{}` part and only prefix the target variable with the `$` sign.

For example:

“ The name is: $firstName”

Here the firstName is a variable and we want to mix in its value into this string.

## Example: Assigning String Template to Variable

``` line-numbers
fun main(){
var fullName = "John Doe"
var age = 100
var result = "The name is: $fullName the age is: ${age}"
println(result)
}
Output:
The name is: John Doe the age is: 100
```

As you can see, String Templates help us to involve the value of variables in the process of creating a new string value in Kotlin.

So here we’ve created a new string value using the values of the fullName and age variables and then stored the result in to the `result` variable which we then passed to the println function in order to see the result.

## Example: passing String Template as Argument to Functions

``` line-numbers
fun main(){
var fullName = "John Doe"
var age = 100
printName("The name is: ${fullName} the age is: ${age}")
}
fun printName(value:String){
println(value)
}
Output:
The name is: John Doe the age is: 100
```

The purpose of using String Template is to create a new string value using the values of other variables. After the string value is created, it doesn’t matter where we want to send this value! It could be a variable of type String or as the argument of a function that needs a string value!

Note: It’s OK if you’re not familiar with functions yet! In *the Kotlin function section* we’ve explain this concept in great details.
