var title: String
At first glance, this may look strange to Java developers, but this construct is a building block of a very important feature of Kotlin called type inference. Type inference means that the compiler can infer type from context (the value of an expression assigned to a variable). When variable declaration and initialization is performed together (single line), we can omit the type declaration. Let's look at the following variable definition:
var title: String = "Kotlin"
