    Re: How to use Map

    There are no templates in Java 1.4, which are called 'Generics'. They are part of Java 1.5.

    What do you mean by "What is objects?"? There are thousands of sites to find out how to use a Map.
    Anyway, a simple example:
    // Create
    Map myMap = new HashMap();
    // Set data
    myMap.put("1", "One");
    myMap.put("2", "Two);
    myMap.put("3", "Three");
    //Get data
    String name = (String) myMap.get("1");
    Please, correct me. I'm just learning.... and sorry for my english :-)
