继续，并与一个扩展范围破 [英] continue and break with an extended scope

问题描述

是否有可能为继续或破发有比当前正在运行的循环更大的范围有多大？< BR> 在下面的例子中，我渴望继续在外部for循环时 EXPR 是真实的，虽然它是所谓的内部进行循环，因此，无论是 [某种内在code] 和 [一些外code] 被执行。

Is there a possibility for a continue or break to have a bigger scope than the currently running loop?
In the following example, I desire to to continue on the outer for-loop when expr is true, although it is called in the inner for-loop, so that neither [some inner code] nor [some outer code] is executed.

for(int outerCounter=0;outerCounter<20;outerCounter++){
   for(int innerCounter=0;innerCounter<20;innerCounter++){
      if(expr){
         [continue outer];    // here I wish to continue on the outer loop     
      }
      [some inner  code]
   }
   [some outer code]
}

在上述

推荐答案

您可以使用 GOTO 如果你绝对必须。不过，我通常采取两种方法之一：

You can use goto if you absolutely must. However, I typically take one of two approaches:

• 请内环一个单独的方法返回布尔，这样我可以从它返回，并指出哪些外环应该做的（休息，继续，或做休息循环体）
• 在保持独立的布尔标志，它是内循环之前设置，可能会被修改的在的内循环，然后被选中的在的内环

• Make the inner loop a separate method returning bool, so I can just return from it and indicate what the outer loop should do (break, continue, or do the rest of the loop body)
• Keep a separate bool flag which is set before the inner loop, may be modified within the inner loop, and then is checked after the inner loop

这些方法我的一般的preFER的提取方法的方法。

Of these approaches I generally prefer the "extract method" approach.
