The path to kotlin growth and the path to kotlin Learning

Preface:

Starting from Kotlin, that is, my decision to start writing a technical blog today, I have a poor literary talent. Thank you for your understanding and guidance. This article is my guide to Kotlin growth for the most bloggers. Therefore, the content is generally the contents of the Kotlin technical blog's directory pages and personal comments, which will be continuously updated.

2017 Google I/O conference: announcing Kotlin as a first-level Android development language

When I heard this message, I was inexplicably reminded of Saipan: The University is a "Mobile Application Development Direction" Major in software engineering. After studying Saipan, I thought that Saipan would do development, however, after graduation, it was not the R & D career of Saipan language, but the start of Android. After a few years, now the Kotlin language has come out.

What is Kotlin: Kotlin is a static type programming language executed on a Java virtual machine. It is mainly developed by the JetBrains development team in St. Petersburg, Russia. The language has several advantages: Concise: It greatly reduces the number of sample codes you need to write. PS: improves readability Security: Avoid NULL pointer exceptions and other errors of the entire class. PS: during compilation, the compiler checks for unforeseen null pointers. If so, compilation fails. Features:1. Static strong type 2. NULL pointer type check 3. Support for functional programming: Lambda 4, coroutine 5, and extension methods General: Build server-side programs, Android applications, or front-end programs running in a browser. Interoperability: Uses the existing JVM frameworks and libraries through 100% Java interoperability. PS: You can use the existing java library in Kotlin, or call java methods or java class implementation interfaces in Kotlin, as well as java annotation, you can also call the Kotlin code in java code.
