Usage

From source file:Set1.java

public static void test(Set s) {
    // Strip qualifiers from class name:
    System.out.println(s.getClass().getName().replaceAll("\\w+\\.", ""));
    fill(s);//  w ww . j a  va  2s  .  c o  m
    fill(s);
    fill(s);
    System.out.println(s); // No duplicates!
    // Add another set to this one:
    s.addAll(s);
    s.add("one");
    s.add("one");
    s.add("one");
    System.out.println(s);
    // Look something up:
    System.out.println("s.contains(\"one\"): " + s.contains("one"));
