I have the code:
for(int i = 0; i < 99999; i++) {
minhaLista.get(i + x); //x é int e possui um valor qualquer
}
At some point the sum of i + x results in a value greater than the size of the list.
If I execute this code I will get a IndexOutOfBoundsException .
What is the best deal for this case?
Should I check for every iteration if (i + x) < minhaLista.size() ? Or should I catch the IndexOutOfBoundsException ?
Unless you have a good reason for doing so, you do not have to capture a IndexOutOfBoundsException , most of the native java exceptions serve only as a warning to the programmer about issues that need to be fixed, not captured .
You yourself answered the question, the most plausible solution is to check that the sum does not exceed minhaLista.size() -1 , this already solves the problem without having to deal with unnecessary catches, leaving the code simpler.
As for capturing RunTimeException , there's a other question here on the site that explains why you should avoid and some situations that may occur when catching more generic exceptions like this or Exception .
For your case the best would be an if before myList.get (i + x);
for(int i = 0; i < 99999; i++) {
if((i + x) < minhaLista.size()){
minhaLista.get(i + x); //x é int e possui um valor qualquer
}
}
