Java规范 [英] Java specification

问题描述

Java JDK或JRE或两者都是规范？
有人可以引用一些相关的实现吗？

Java JDK or JRE or both are specifications? Can anyone quote some relevant implementations?

推荐答案

JDK（Java Developer Kit）和JRE（Java运行时环境）是（部分） Java语言规范和 Java虚拟机规范。根据上下文，JRE和JDK可能会也可能不会引用Sun JRE和Sun JDK。您可以看到此JVM列表（Java虚拟机）。还有第三方java编译器，最流行的是ecj和gcj。

The JDK (Java Developer Kit) and JRE (Java Runtime Environment) are (in part) both implementations of the Java Language Specification and The Java Virtual Machine Specification. JRE and JDK may or may not refer to the Sun JRE and Sun JDK depending on context. You can see this list of JVMs (Java Virtual Machines). There are also third-party java compilers, the most popular being ecj and gcj.
