Iterate a treemap from specific key to end of map

    TreeMap treemap=new TreeMap<String,double>();
    treemap.put("02.00", 7.5);
    treemap.put("03.30", 7.9);
    treemap.put("04.00", 8.0);
    treemap.put("05.30", 6.8);
    treemap.put("10.00", 9.01);
    treemap.put("11.30", 8.9);
    treemap.put("12.00", 9.30);
    System.out.println(treemap);
    double min=(double) Collections.min(treemap.values());

Treemap contains -- {02.00=7.5, 03.30=7.9, 04.00=8.0, 05.30=6.8, 10.00=9.01, 11.30=8.9, 12.00=9.30} min contains value : 6.8

Now i want to iterate key and value after 

 treemap.put("05.30", 6.8);

i.e., 

  treemap.put("10.00", 9.01);
  treemap.put("11.30", 8.9);
  treemap.put("12.00", 9.30);

and store last three map key and value in another treemap..

TreeMap has a method tailMap(K fromKey) which returns a SortedMap<K, V> whose keys are greater than / equal to K.
