An easy way to initialize a set without manually adding each element

import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;

public class MainClass {

public static void main(String[] a) {
String elements[] = { "A", "B", "C", "D", "E" };
Set set = new HashSet(Arrays.asList(elements));

System.out.println(set);

}

}
