禁止空块语句和静态块。

¥Disallow empty block statements and static blocks.

空静态块和块语句虽然在技术上不是错误，但通常是由于未完成的重构而发生的。它们可能会在阅读代码时造成混淆。

¥Empty static blocks and block statements, while not technically errors, usually occur due to refactoring that wasn’t completed. They can cause confusion when reading code.

此规则不允许空块语句和静态块。此规则忽略包含注释的块语句或静态块（例如，在 try 语句的空 catch 或 finally 块中，以指示无论是否有错误都应继续执行）。

¥This rule disallows empty block statements and static blocks. This rule ignores block statements or static blocks which contain a comment (for example, in an empty catch or finally block of a try statement to indicate that execution should continue regardless of errors).
