主要是解决Java之前被诟病已久的问题，而且积极借鉴了 Scala、Ruby 等新语言在开发效率和简洁性上的优势...
精简语法和简明 Lean Syntax and Concise – 一个线程函数需要一行,简单的结构体/ JavaBeans也可以在一行中声明。 实际的属性在Java互操作的后台生成getter和setter。 并且将数据注释添加到类中会触发自动生成样板,如equals,hashCode,toString等等。 考虑以下示例 – 你也可以喜欢在Docker和Kubernetes上部署Kotlin应用程序...
Lean Syntax and Concise - One liner functions take one line, simple structs/JavaBeans can also be declared in one line. Real properties generate getters and setters behind the scenes for Java interop. And Adding the data annotation to a class triggers autogeneration of boilerplate like equals,...
Kotlin and Java are both general-purpose, statically typed programming languages. In many ways, Kotlin is considered a replacement for Java. While it is not compatible with syntax, it isinteroperable with Java codeand libraries. Kotlin also has its own libraries that were created through an appli...

一、 命名格式 总体来说,Kotlin命名格式要和Java命名规范保持一致,因为Kotlin也是JVM兼容的语言。 包名 包的命名规则和Java一样:全小写,当遇到多个词连接...
(width * length) } // Alternative one liner Getter/Setter Syntax var volume2: Int get() = width * height * length / 1000 // By convention, the name of the setter parameter is " value " private set(value) { height = (value * 1000) / (width * length) } // If we didn't ...
pledging to support the language going forward. Kotlin as a language has a lot of similarities to Java in structure. Moreover, Kotlin adds a lot of nice-to-have features, a much cleaner syntax, ideas from functional programming, and other enhancements over Java. Come to VS Code and hav...
Since Kotlin is supposed to be interoperable with Java and is is a valid method (identifier) name in Java, the backticks are used to escape the method so that it can be used as a method without confusing it as a keyword. Without it it will not work because it would be invalid syntax...
), not to mention a lack of support for functional programming features. Although Java is starting to add some functional programming elements, such as lambda expressions and functional interfaces, at its core Java is still a procedural language. Java’s syntax is also pretty verbose, particularly...
