java - Break 语句突然完成还是正常完成？

Question

JLS 14.15:

A break statement with no label attempts to transfer control to the innermost enclosing switch, while, do, or for statement of the immediately enclosing method or initializer;

我对该规则有误解。例如，如果我们编写代码:

public static void main(String[] args) // Immediately enclosing method
{
    while(true){                       // Innermost enclosing 'while' for the break at LINE 2?
        break;                         // **LINE 2**
    }
} 

JLS 说，当我们在 LINE 2 时，我们尝试将控制权转移到最内层的 while。做什么的？在 LINE 2 处，控制已经位于 while 的 block-statement 处。

Answer 1

您需要检查您引用的整个段落(为了清楚起见，我突出显示了粗体中的句子):

A break statement with no label attempts to transfer control to the innermost enclosing switch, while, do, or for statement of the immediately enclosing method or initializer; this statement, which is called the break target, then immediately completes normally.

在您的示例中，控制权转移到 while 语句以便终止并继续执行。
