This is used to skip inside an iteration.
An example for this is the following for loop statement that prints all even numbers from 0 - 10.
for(int num = 0;num <= 10; num++){ if ((num % 2) > 0) continue; printf("%d ", num); }
The code is written in C Language (actually it is more like an algotithm)
so even JAVA programmers can easily translate them.
Another example, for more sophisticated programming, continue may be also used for deleting entries in file manipulation.
