I agree. The static variable sm_instance would be GC'd during the lifetime of the class only if it is explicitly null assigned. -- Radz Bill Littman wrote: Devashish- I may have misunderstood what you are saying, but the private static LogManager object is not being Garbage Collected. There is a reference to it throughout the life of your program, so it will never be GC'ed. Hope this helps. -Bill Littman -----Original Message----- From: devashish bajpai [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 18, 2004 7:06 AM To: Bill Littman Cc: [EMAIL PROTECTED] Subject: Re: RE: (no subject) i dont think that the problem is only of synchronisation . The problem is with Garbage Collection that collects the object as i use the SingeTon object without reference(see at the bottom how i m using it ) . thus Garbage Collection is taking place ...what can i do to keep the code of my project unchanged ..

Also not sure if it *actually* helps much but you could check out Double checked locking idiom too. -- Radz devashish bajpai wrote: i have a proble i have made a class SingleTon .. i use it in many places in my project .. but just have relised that the calss is creating more intances ...the code is as following .... public class LogManager { private java.io.PrintStream m_out; private LogManager( PrintStream out ) { m_out = out; } public void log( String msg ) { System.out.println( msg ); } static private LogManager sm_instance; static public LogManager getInstance() { if ( sm_instance == null ) sm_instance = new LogManager( System.out ); return sm_instance; } } and using it like this ...
