Kotlin

Kotlin-1

Kotlin is an elegant general-purpose language with a rich syntax that enables us to write concise and expressive code. Much of its appeal also stems from the fact that it is fully interoperable with Java and has multi-platform support. Kotlin is also an official Android language ranked by Google as the most preferred language for Android app development.

In this course, you’ll learn about type inference in Kotlin as well as about Kotlin’s support for higher-order functions. You’ll cover classes, objects, and other interesting themes relevant to these topics. You’ll finish with operator overloading, extension functions, and scoping functions.

This course is specially designed for Java professionals who want to get into Kotlin development with minimal time and effort. This is not an encyclopedic work on Kotlin. Rather, it focuses on the necessary foundations and the best features that Kotlin has to offer. After completing this course, you’ll feel more comfortable reading and writing Kotlin code.

Kotlin Compact

Let’s have a look at the four things we don’t need in Kotlin.
## No semicolon necessary

In Kotlin, a semicolon (`;`) to terminate a statement is not mandatory.

In contrast to Java and other languages, the Kotlin compiler usually recognizes the end of a statement even without an explicit `;`, for example, by a line break.

>**Note:** The general rule in Kotlin is not to use semicolons.

However, two marginal exceptions should be noted.


### Multiple expressions in the same line
If we want to note several statements in a single line, they are separated with `;`.
