Java是一种字节编译语言，目标是一个叫做Java虚拟机的平台，它是基于堆栈的，在许多平台上都有一些非常快速的实现。

Java被编译成字节码，然后进入Java VM，由其解释。

Java是一种编译的编程语言，但它不是直接编译为可执行的机器代码，而是编译为一种称为JVM字节代码的中间二进制形式。然后对字节码进行编译和/或解释以运行程序。

Application developers can develop the application code on any of the various OS that are available in the market today. Java language is agnostic at this stage to the OS. The brilliant source code written by the Java Application developer now gets compiled to Java Byte code which in the Java terminology is referred to as Client Side compilation. This compilation to Java Byte code is what enables Java developers to ‘write once’. Java Byte code can run on any compatible OS and server, hence making the source code agnostic of OS/Server. Post Java Byte code creation, the interaction between the Java application and the underlying OS/Server is more intimate. The journey continues - The enterprise applications framework executes these Java Byte codes in a run time environment which is known as Java Virtual Machine (JVM) or Java Runtime Environment (JRE). The JVM has close ties to the underlying OS and Hardware because it leverages resources offered by the OS and the Server. Java Byte code is now compiled to a machine language executable code which is platform specific. This is referred to as Server side compilation.

所以我认为Java绝对是一种编译语言。

术语“解释语言”或“编译语言”没有意义，因为任何编程语言都可以解释和/或编译。

对于Java的现有实现，大多数都涉及到字节码的编译步骤，因此它们涉及到编译。运行时还可以动态加载字节码，因此总是需要某种形式的字节码解释器。 该解释器可能会也可能不会在内部使用对本机代码的编译。

如今，部分即时编译被用于许多曾经被认为是“解释型”的语言，例如JavaScript。

两者都有。首先，java编译(有些人更喜欢说“翻译”)字节码，然后根据JIT的情绪进行编译或解释。
