java - "immediately completes normally"对 if 语句意味着什么？

Question

“立即正常完成”是否意味着实际上绕过了 if 语句并且不评估其条件？

编辑:

为了理解 Java 规范中与 if 语句相关的短语 iteself，我特意省略了一个示例。

但似乎没有人在这种情况下考虑过这个短语。

所以这是一个演示程序。

import java.io.*;

class TestBreakWIthLabel
{
    public static void main (String[] args) throws java.lang.Exception
    {
        int x = 1;

        L:if ( x++ < 2 ) break L;

        System.out.println( "x = " + x );
    }
}

但是，如果有人会针对该程序提供他的“解释”，那可不是个好主意。我想独立于程序示例了解该短语的含义。

这是规范(14.15 中断语句)中的相应引用。

A break statement with label Identifier attempts to transfer control to the enclosing labeled statement (§14.7) that has the same Identifier as its label; this statement, which is called the break target, then immediately completes normally. In this case, the break target need not be a switch, while, do, or for statement.

假设您指的是 this part of the JLS

A break statement with label Identifier attempts to transfer control to the enclosing labeled statement (§14.7) that has the same Identifier as its label; this statement, which is called the break target, then immediately completes normally. In this case, the break target need not be a switch, while, do, or for statement.

其中 break 目标是一个 if 语句，然后封闭的标记语句是 if 语句并且它的条件已经被评估，因为你在它的体内，它的 contained Statement。它不会在完成 时再次计算。
