Package java.util
Class TreeMap
Description:
Returns the value to which this map maps the specified key. null is returned, if the map contains no mapping for this key. A return value of null dose not necessarily indicate that the map contains no mapping for this key. It's also possible that the map explicitly maps the key to null.
Example
TreeMap treeMap = new TreeMap();
treeMap.put("1", "T");
treeMap.put("2", "r");
treeMap.put("3", "e");
treeMap.put("4", "e");
treeMap.put("5", "M");
treeMap.put("6", "a");
treeMap.put("7", "p");
Logger.log("TreeMap: " + treeMap.get("2"));
The example above returns the second element in this map.
