Refactoring a nested loop
- by user3517441
I have the following code which I use a lot of times in the class.
for (int i = 0; i < someList.size(); i++) {
for (int j = 0; j < someList.size(); j++) {
if (i != j) {
someList.get(i).sendMessageTo(someList.get(j))); //variable action
}
}
}
The purpose of the loop is to make each element in the List to send a message (or perform another action) to every element in the list except itself.
Is there any way I can create a helper method so I don't have to repeat the loop code.
I want to be able to state the variable action and call the helper method.
Thanks.
