如何在双/嵌套循环中脱离主/外循环?

如果我在循环中有循环，并且一旦满足 if 语句，我想中断主循环，我该怎么做?

If I have loop in a loop and once an if statement is satisfied I want to break main loop, how am I supposed to do that?

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. } } } }

推荐答案

使用带标签的中断:

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