Usage

From source file:Main.java

public static void main(String[] args) {
    NavigableMap<Integer, String> nmap = new TreeMap<Integer, String>();
    nmap.put(1, "this");
    nmap.put(2, "is");
    nmap.put(3, "a");
    nmap.put(4, "test");
    nmap.put(5, ".");

    System.out.println(nmap);/*ww w .  j  av  a 2 s .co m*/
    System.out.println(nmap.subMap(4, true, 5, true).values());
    nmap.subMap(1, true, 3, true).clear();
    System.out.println(nmap);
    // wrap into synchronized SortedMap
    SortedMap<Integer, String> ssmap = Collections.synchronizedSortedMap(nmap);

    System.out.println(ssmap.subMap(4, 5));
    System.out.println(ssmap.subMap(4, 5 + 1));
