java - Compilation error, list not recognised -

i using trove collections, , more specifically, primitive arraylist ints.

the declaration of list follows:

tintarraylist list= new tintarraylist(); 

however, facing compilation error cannot explain. when declare list follows:

import gnu.trove.list.array.tintarraylist;  public class main {     tintarraylist list= new tintarraylist(); } 

, code runs correctly expected. however, when declare list (with different import statement) follows:

import gnu.trove.*;   public class main {      tintarraylist list= new tintarraylist(); } 

, compilation error appears not recognising tintarraylist.

i wondering why error appears? thought using * list should recognized. error doesn't appear when java.util.*; used instead of java.util.arraylist;.

the difference * not import sub-levels, in current level. if used import gnu.trove.list.array.*, work expect.

the reason works on java.util.* because arraylist class in same folder wildcard.
