WebJava虚拟机只与由字节码组成的Class文件进行交互。 我们说Java语言可以“Write Once,Run Anywhere”,这里的Write其实指的就是生成Class文件的过程。 因为Java Class文件可以在任何平台创建,也可以被任何平台的Java虚拟机装载并执行,所以才有了Java的平台无关性。 Write once, run anywhere (WORA), or sometimes Write once, run everywhere (WORE), was a 1995 slogan created by Sun Microsystems to illustrate the cross-platform benefits of the Java language. Ideally, this meant that a Java program could be developed on any device, compiled into standard bytecode, and be expected to run on any device equipped with a Java virtual machine (JVM). The installation of a JVM or Java interpreter on chips, devices, or software pac…
