Android Development with Kotlin

String templates

Building strings is an easy process, but in Java it usually requires long concatenation expressions. Let's jump straight to an example. Here is a string built from multiple elements implemented in Java:

//Java 
String name = "Eva"; 
int age = 27; 
String message = "My name is" + name + "and I am" + age + "years old";

In Kotlin, we can greatly simplify the process of string creation by using string templates. Instead of using concatenation, we can simply place a variable inside a string, using a dollar character to create a placeholder. During interpolation, string placeholders will be replaced with the actual value. Here is an example:

 val name = "Eva" val age = 27 val message = "My name is $name and I am $age years old" println(message) ...
