From source file:Tutorial.java

public static void main(String[] args) {
    EnumMap<Tutorial, String> map = new EnumMap<Tutorial, String>(Tutorial.class);

    map.put(Tutorial.CSS, "1");
    map.put(Tutorial.Python, "2");
    map.put(Tutorial.PHP, "3");
    map.put(Tutorial.Java, "4");

    System.out.println(map);/*from w  w w . ja  v  a2s.  c o m*/

    System.out.println("Number of mappings:" + map.size());

    map.put(Tutorial.Javascript, "5");

    // print the new number of mappings of this map
    System.out.println("Number of mappings:" + map.size());
}
