But if you can tell me whether immutable objects are garbage collected with one simple example it will be great.

Thanks
Arnab

You are right that String s = "dasdsa"; will create only one object and that too in pool bu with String s1 = new String("dasda"); will create one object in non-pool and the one reference in pool which will refer to non-pool object.

But I think we are diverting from the actual question that I have put. If anybody can explain me when these will be garbase collected, I will be thankful.

Hi All,

I have got a confusion regarding the garbage collection of any immutable class including String,Integer etc. Can anyone give me one small example explaining this.

If do the following :

Case 1:
String s1 = "123"; //line 1
s1 = "abc"; // line 2
//line 3
At line 3 how many objects are elligible for garbase collection.

Case 2:
String s2 = new String{"123"); //line 1
s2 = new String("abc"); // line 2
//line 3
At line 3 how many objects are elligible for garbase collection.

Case 3:
Integer i1 = new Integer("123"); //line 1
i1 = new Integer("567"); // line 2
At line 3 how many objects are elligible for garbase collection.

Appreciate your help.

Thanks

Sorry for leaving some part of the question.
Can we call the synchronized blocks of the object?

Please consider the following codes :

synchronized(object) {
try {
Thread.sleep(100000);
} catch(InterruptedException e) {
}
}

If this is a code which is executed by a thread, then as far as sleep's specification is concerned, it will not free the lock which is currently on object.

Is it possible to use the "object" to do some other opnerations on it?

Thanks

I have checked in the webapps directory of tomcat installation and have found that the DR_Tool is not installed in that directory.

Please let me know if I am doing anything wrong which is creating this problem.

Hi All,

I am developing a client server software where I found a typical type of problem. The is one session bean n the project. When two persons login into the system with the same userID, an abnormal behaviour starts. The usual flow is disturbed. It creates those types of entries in the database which it should not be. Do you have any idea about the scenario behind this. Is there any conflict of remote session instance being created in EJB container for the same userID.

Thanks in advance.

Arnab

But how do i fix it.
