Java 教程 表达式的不完整定义

Question

expressions 的 Java 教程说的是

expression is a construct made up of variables, operators, and method invocations

为什么文字不包含在此列表中？

Answer 1

Java Language Specification状态:

15.8. Primary Expressions

Primary expressions include most of the simplest kinds of expressions,from which all others are constructed: literals, class literals, fieldaccesses, method invocations, and array accesses. A parenthesizedexpression is also treated syntactically as a primary expression.

这应该是您寻找 java.lang.java 的定义或规范时的起点。教程或某些 API 文档注释(这就是 JavaDoc)不能用来反对同样的完整性声明。
