2.5. Distributed Set

Distributed Set is distributed and concurrent implementation ofjava.util.Set. Set doesn't allow duplicate elements, so elements in the set should have proper hashCode and equals methods.

import com.hazelcast.core.Hazelcast;
import java.util.Set;
import java.util.Iterator;

java.util.Set set = Hazelcast.getSet("IBM-Quote-History");
set.add(new Price(10, time1));
set.add(new Price(11, time2));
set.add(new Price(12, time3));
set.add(new Price(11, time4));
//....
Iterator it = set.iterator();
while (it.hasNext()) { 
    Price price = (Price) it.next(); 
    //analyze
