Hi all,
Java.util.Vector is a synchronized class. I checked the syntax of all methods in Vector class, but no method signature include synchronized keyword.

My question is how can we create a synchronized class?

In synchronized class wheather class is synchronized or both class and all methods are synchronized?

Thanks in advance.

The term "synchronized class" actually doesn't really exist. Vector is *thread safe*. There are several ways to make a class thread safe, the synchronized modifier is just one tool in the toolbox to do that.

This really is a topic for a whole book, but techniques to make a class thread safe include using synchronized methods, synchronized blocks and volatile fields. Java 5 also added a lot of additional classes that help with this topic.

If you want to know how it's done in the Vector class, you should probably start by looking at its source code, which comes with the JDK.
