Constants - final static fields and occasionally final local variables - are written in all uppercase with underscores separating the words, as in MAX_CONNECTIONS.

常量—终态静态字段和临时终态本地变量—全部适用大写字母，并以下划线分隔各词，如MAX_CONNECTIONS。

One final improvement I want to make on this dynamic class is to use member variables to access the fields, instead of the clunky get_ and set_ operators.

对这个动态类我想做的最后一个改进，是用成员变量访问字段，而不是用笨重的get _和set _操作符。

One limitation of inner classes - and lambda expressions too - is that they can only refer to final local variables from their lexical scope.

内部类以及lambda表达式一个局限性是——它们只引用来自它们的词法作用域的最终(final)局部变量。
