Hello Kotlin!
大家都说:kotlin是Android世界的Swift 。
欧耶,很好很好,要好好的研究学习下了。
目前其最新的版本是 Kotlin 1.0 。于2016年2月15日发表。
一:Kotlin 是什么?
对呀,kotlin到底是什么呢?根据官方描述:
Kotlin is a pragmatic programming language for JVM and Android that combines OO and functional features and is focused on interoperability , safety , clarity and tooling support.
其可以运行于以下的工具(引用官方原句):
1.IntelliJ IDEA, Android Studio and Eclipse
2.Maven, Gradle and Ant
3.Spring Boot(Kotlin support released today!)
4.GitHub, Slack and even Minecraft
Kotlin的亮点在于:
One of the key focuses of Kotlin has been interoperability and seamless support formixed Java+Kotlin projects, making adoption easier leading to less boilerplate code and more type-safety. Additionally, Kotlin has anextensive standard librarythat makes everyday tasks easy and smooth while keeping the bytecode footprintlow. Of course,any Java library can be used in Kotlin, too; and vice versa.
好吧,Kotlin的介绍多得不要不要的。#— 。—#
