The convention for packages is different from the Java naming conventions used for variables, methods and reference types. Packages are always written in lowercase letters, with a dot between words. A Java package is actually a reference to the file system. The dot in a package name maps to ...

以CaseFormat.LOWER_HYPHEN为例,注释如下: /** Hyphenated variable naming convention, e.g., "lower-hyphen". */ 代表连字符的变量命名规范,例如user-name,user-age等。 为了减少大家的阅读源码的工作量,这里把5个枚举及意义都拿出来说一下。 | 枚举变量 | 说明 | | --- | --- | | CaseFormat.LOWER...
If the name you choose consists of only one word, spell that word in all lowercase letters. If it consists of more than one word, capitalize the first letter of each subsequent word. The names gearRatio and currentGear are prime examples of this convention. If your variable stores a consta...
Variable names are case-sensitive. A variable's name can be any legal identifier — an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign "$", or the underscore character "_". The convention, however, is to always begin your variable names wit...
Variable names should be short yet meaningful. The choice of a variable name should be mnemonic- that is, designed to indicate to the casual observer the intent of its use. One-character variable names should be avoided except for temporary "throwaway" variables. Common names for temporary varia...

if ("John".equals(name)) { System.out.println("His name is John"); } We compare the name variable to the "John" string. Notice that we call the equals method on the "John" string. This is because if the name variable equals to null, calling the method would lead to NullPointer...
2The naming convention of the interface was to append Source to the semi-traditional class name. There is no FlowableSource since Publisher is provided by the Reactive Streams library (and subtyping it wouldn't have helped with interoperation either). These interfaces are, however, not standard ...
