java - 所包含的声明是什么？

Question

JLS 14.21用于无法到达的语句的规则的描述中，某些包含的语句。为了更具体，我将引用一段话:

A while statement can complete normally iff at least one of the following is true:

• The while statement is reachable and the condition expression is not a constant expression (§15.28) with value true.

• There is a reachable break statement that exits the while statement.

The contained statement is reachable iff the while statement is reachable and the condition expression is not a constant expression whose value is false.

我怀疑这只是一段时间的整个 block 语句，例如以下内容:

while(true){
    //Something
}

这就是包含语句，由括号括起来的所有代码组成，是吗？

Answer 1

在您的示例中，包含的语句将是 \\something ，即循环体。如果您阅读JLS #14.12表达式包含语句也被使用，并且它的含义在该上下文中可能更清晰。
