    languages.put(3, "JavaScript");
    System.out.println("HashMap: " + languages);

    // iterate through keys only
    System.out.print("Keys: ");
    for (Integer key : languages.keySet()) {
      System.out.print(key);
      System.out.print(", ");
    }

    // iterate through values only
    System.out.print("\nValues: ");
    for (String value : languages.values()) {
      System.out.print(value);
      System.out.print(", ");
    }
    
    // iterate through key/value entries
