java - 如何在双/嵌套循环中脱离主/外循环？

Question

这个问题在这里已经有了答案:

How do I break out of nested loops in Java? (37 个回答)

如果我在循环中有循环，并且一旦满足 if 语句我想打破主循环，我应该怎么做？

这是我的代码:

for (int d = 0; d < amountOfNeighbors; d++) {
    for (int c = 0; c < myArray.size(); c++) {
        if (graph.isEdge(listOfNeighbors.get(d), c)) {
            if (keyFromValue(c).equals(goalWord)) { // Once this is true I want to break main loop.
                System.out.println("We got to GOAL! It is "+ keyFromValue(c));
                break; // This breaks the second loop, not the main one.
            }
        }
    }
}

使用带标签的中断:

mainloop:
for(){
 for(){
   if (some condition){
     break mainloop;
   }
  }
}
