Possible to use break for outer loop?

Question

If I use break like the code below, then the loop within row won't iterate the rest if there is a match in the beginning, but what about the col loop?

Would it still iterate between 0 and 7? Is there a way to use break there as well?

for (int col = 0; col < 8; col ++)     for (int row = 0; row < 8; row ++)         if (check something)         {             //Then do this;             break;         } 

Answer 1

One option is to use a condition flag. You could then either break in the outer loop as well, or just use it as an extra condition within the for loops:

bool keepGoing = true;  for (int col = 0; col < 8 && keepGoing; col++) {     for (int row = 0; row < 8 && keepGoing; row++)     {         if (something)         {              // Do whatever              keepGoing = false;         }     } } 

In Java, you can specify a label to break to though. (I didn't see that this question was tagged Java as well as C#.)

outerLoop: for (...) {     for (...)     {         if (...)         {             break outerLoop;         }     } } 

EDIT: As noted in comments, in C#, you could use a label and goto:

for (...) {     for (...)     {         if (...)         {             goto endOfLoop;         }     } } endOfLoop: // Other code 

I'd really recommend that you don't take either of these approaches though.

In both languages, it would usually be best to simply turn both loops into a single method - then you can just return from the method:

public void doSomethingToFirstOccurrence() {     for (...)     {         for (...)         {             if (...)             {                 return;             }         }     } }

Yes, it is possible by using a break label:

package others;  public class A {      public static void main(String[] args) {         outer: for(int col = 0; col < 8; col ++)         {             for (int row = 0; row < 8; row ++)             {                 if (col == 4)                 {                     System.out.println("hi");                     break outer;                 }             }         }     } }
