A Java class file is a file (with the .class filename extension) containing Java bytecode that can be executed on the Java Virtual Machine (JVM). ... If a source file has more than one class, each class is compiled into a separate class file. ...
URL以斜杠/ 结尾,且协议名是file,则使用FileLoader 来寻找类,即为在本地文件系统中寻找.class文件 URL以斜杠/ 结尾,且协议名不是file,则使用最基础的Loader 来寻找类,我们正常开发的时候通常遇到的是前两者,那什么时候才会出现使用Loader 寻找类的情况呢?当然是非file 协议的情况下,最常见的就是http 协议。 作为...
After all the compilation on the programmer’s host machine is completed, the remaining target code file is commonly referred to as an object file and can contain anything from machine code to Java byte code (discussed later in this section), depending on the programming language used. As show...

Java字节码(Java Bytecode)是Java编译器将Java源代码编译后生成的一种中间表示形式。Java字节码并不是直接运行在物理机器上的指令,而是运行在Java虚拟机(JVM)上的一组指令集。Java字节码具有平台无关性,这意味着它可以在任何安装了JVM的设备上运行,而不需要重新编译。
