Your program should work exactly the same with either import java util    or import java util Date   There has to be something else you did in between

You probably have some other  Date  class imported somewhere  or you have a Date class in you package  which does not need to be imported   With  import java util    you are using the  other  Date  In this case it s best to explicitly specify java util Date in the code   Or better  try to avoid naming your classes  Date

but what I got is something like this  Date 124bbbf   while I change the import to  import java util Date    the code works perfectly  why     What do you mean by  works perfectly   The output of printing a Date object is the same no matter whether you imported java util   or java util Date  The output that you get when printing objects is the representation of the object by the toString   method of the corresponding class

import java util      imports everything within java util including the Date class   import java util Date    just imports the Date class   Doing either of these could not make any difference

The toString   implementation of java util Date does not depend on the way the class is imported  It always returns a nice formatted date   The toString   you see comes from another class   Specific import have precedence over wildcard imports   in this case  import other Date import java util    new Date      refers to other Date and not java util Date   The odd thing is that  import other   import java util     Should give you a compiler error stating that the reference to Date is ambiguous because both other Date and java util Date matches
