With array, we can easily declare and initialize it at the same time:

String[] favorites = new String[] {"EJB", "JPA", "Glassfish", "NetBeans"};

Or even simpler:

String[] favorites = {"EJB", "JPA", "Glassfish", "NetBeans"};
We can do the same with a List using java.util.Arrays.asList method. For example:

package javahowto;

import java.util.Arrays;
import java.util.List;

public class ListTest {
  public static final List<String> favorites =
        Arrays.asList("EJB", "JPA", "Glassfish", "NetBeans");

  public static void main(String[] args){
      System.out.println("favorites: " + favorites);
  }
}
