java - Extract String value from a TreeMap -

map 1 treemap , map2 hashmap

how extract value (string3[]) in string array treemap (map1) in java. treemap of type map1<string1,map2<string2,string3[]>>

i have used treemap.getkey().contains(string2) key of string 2. need extract values of corresponding key i.e. string2 , store them in string array.

collection entryset = treemap.entryset();      // obtain iterator entries set     iterator = entryset.iterator();      // iterate through treemap entries     system.out.println("treemap entries : ");     while(it.hasnext())  system.out.println(it.next());   }
