Java链接器如何工作? [英] How Java linker works?

问题描述

我想知道Java链接程序是如何工作的.具体来说，它将类，接口，包，方法等以何种顺序组合为jvm可执行格式.我在此处找到了一些信息，但事实并非如此.有关链接顺序的很多信息.

I want to know how Java linker works. Specifically, in which order it combines classes, interfaces, packages, methods and etc into jvm-executable format. I have found some information here, but there is not so much information about linking order.

推荐答案

没有Java链接器"之类的东西.但是，存在类加载器的概念，该类加载器给定"somewhere"中的java字节代码数组，可以创建类的内部表示形式，然后可以与new等配合使用.

There is no such thing as a Java "linker". There is, however, the concept of a classloader which - given an array of java byte codes from "somewhere" - can create an internal representation of a Class which can then be used with new etc.

在这种情况下，接口只是特殊的类.加载类后，即可使用方法和字段.

In this scenario interfaces are just special classes. Methods and fields are available when the class has been loaded.
