The rule of thumb is that you should use the one method that best matches the collection type the application is waiting for, so that type conversions are avoided.

经验法则是，应该使用与应用程序期望的集合类型最匹配的那个方法，以避免类型转换。

For a helpful rule of thumb, you could say that a method with more than 100 non-commenting lines of code is way too long.

有一个很有帮助的经验法则，您可以说非代码注释行超过100行的方法是长方法。

The general rule of thumb is that if there's more than one try-block's worth of code in a method, then the method is too big and should probably be broken up into smaller methods anyway.

主要的实践经验是：如果一个方法中存在多个try块，那么就表明方法过于庞大，应拆分为多个较小的方法。
