guava implement round robin 2020-06-21 06:11
we can use Iterators.cycle of guava to implement round robin. Here is an example.
public class RoundRobinClient {
public static void main(String[] args) {
Iterator<String> cycleIterator = Iterators.cycle(Arrays.asList("A", "B", "C", "D"));
for (int i = 0; i < 10; i++) {
System.out.println(cycleIterator.next());
}
}
}
The output is like following.
A
B
C
D
A
B
C
D
A
B
