How to synchronize an object ???

[AnanthNag.Kundanala]

Hello all,

I know that we can synchronize a method or a block of code in a java class . But what is this synchronized classes ( HashTable) and how to synchronize a nonsynchronized objects to synchronized one ???

[Fubarable]

"Synchronize an object" doesn't make any sense. Can you please elaborate on your question?

Dear Fubarable ,
Here is my detailed question .

In collections , we have two classes ArrayList and Vector .

ArrayList is a non synchronized class and Vector is a synchronized class . Am I right ?

So, what is this synchronized class ???

And I know how to synchronize a method . But I don't know how to synchronize a class similar to that of Vector .

hope you will get me clearly .

There is no such thing as a "synchronized Object". Vector contains some synchronized methods and/or code pieces. That's it. If you want to "synchronize a class", just make sure it is thread safe.

Although, to be fair to the OP, the Vector API does say this: Unlike the new collection implementations, Vector is synchronized.

So , making a class ' Thread Safe ' is nothing but ' Synchronizing a class ' ???

I know how to prepare a class thread safe . Thanks a ton .

uffffff...... OK ... Thank you Kevin and Fubarable.
