What is the difference between a standardwhile(true)loop andfor(;;)? Is there any, or will both be mapped to the same bytecode after compiling? Semantically, they'recompletely equivalent. It's a matter of taste, but I thinkwhile(true)looks cleaner, and is easier to read and understand ...

注意:不同的编程语言或框架的 VS Code 插件可能有不同的 “Call Hierarchy” 支持程度。比如在 JavaScript/TypeScript 或 C++ 中,你可能需要具备最新的插件和语言服务来使用这个功能。在 Java 中,需要安装 “Language Support for Java™ by Red Hat” 插件才能使用这个功能。

处理subList()时,位于fromIndex的元素在子列表中,而位于toIndex的元素则不是,提醒这一点很重要。以下for-loop测试案例大致反映了这一点: for (int i=fromIndex; i<toIndex; i++) { // process element at position i } 此外,我们还应该提醒的是 ― 对子列表的更改(如add()、remove()和set()调用)对底层...
