Inside the new Kotlin file you can create the main routine/function. IntelliJ IDEA comes with a template, so you simply need to write main and press tab to have it appear. Main template When you code is ready, you can compile it and run the program with the proper menu or clicking the...
同时,我们也能知道Kt.class跟Java.class文件有着这个kotlin-runner.jar的逻辑映射上的区别。也就是说,Kotlin的Bytecode跟纯的JVM bytecode存在一个kotlin-runner.jar的映射关系。 像scala,groovy等基于JVM的语言的compiler,runner,基本都采用这种运行方式。在实现细节上也许会有不同,总的思路是一致的。比如说,scalac...

而不需要从class进行派生。第6题：kotlin中的null safety是什么意思？null safety的特性是为了去除null pointer exception在实时运行中的出现风险。它也用来区分空引用和非空引用。第7题：为什么kotlin跟Java具有互相的操作性？因为这两门语言，对于jvm来说没有区别。它们都是编译成byte code, 然后在jvm上运行的。
/** * Starts this coroutine with the given code [block] and [start] strategy. * This function shall be invoked at most once on this coroutine. * * First, this function initializes parent job from the `parentContext` of this coroutine that was passed to it * during construction. Second...
The Kotlin Kernel for notebooks supports running code cells to immediately see outputs, basic code completion, error analysis, and other interactive coding features, enhancing the interactive experience provided by theKotlin REPL. With the Kotlin Kernel for notebooks, you gain access to a range of ...
A script is defined as a Kotlin source file with the file extension .kts that includes executable code. As a simple example, the file southpole.kts in Example 1-5 shows the current time at the South Pole and prints whether it is currently on daylight saving time. The script uses the...
从这个逻辑,我们可以看出,Kt.class在java命令执行前,需要从kotlin-runner.jar这个逻辑里走一遍。同时,我们也能知道Kt.class跟Java.class文件有着这个kotlin-runner.jar的逻辑映射上的区别。也就是说,Kotlin的Bytecode跟纯的JVM bytecode存在一个kotlin-runner.jar的映射关系。其大致执行过程如下图所示: ...
