Usage

From source file:Main.java

public static void main(String[] args) {
    LinkedHashMap<String, Integer> lHashMap = new LinkedHashMap<String, Integer>();

    lHashMap.put("One", new Integer(1));
    lHashMap.put("Two", new Integer(2));

    Object obj = lHashMap.get("One");
    System.out.println(obj);//  w w  w  .  ja v a  2 s .  c  om
}

From source file:Main.java
