Having briefly explored Hazelcast's distributed capabilities via a test console, let's have a look at how we are more likely to interact with a cluster in the real world. Let's create a new SimpleMapExample class with a main method to spin up and manipulate a named distributed map called capitals. Hazelcast refers to these named collections as a namespace. These collections must be uniquely named across the cluster, as follows:
import com.hazelcast.core.Hazelcast;
import com.hazelcast.core.HazelcastInstance;
import java.util.Map;
public class SimpleMapExample {
public static void main(String[] args) {
HazelcastInstance hz = Hazelcast.newHazelcastInstance();
Map<String, String> capitals = hz.getMap("capitals");
capitals.put("GB", "London");
capitals.put("FR", "Paris");
capitals.put("US", "Washington DC");
capitals.put("AU", "Canberra");
System.err.println(
"Known capital cities: " + capitals.size());
System.err...
