Hi Ravi, welcome to the ranch!!

First of all this is in the wrong forum! This forum is for JSP related stuff and your question has more to do with core java.

Now to your question. I think what you meant was how to make operations on an ArrayList synchronized. The ArrayList methods as such are not synchronized. You can either write a wrapper class and synchronize the calls, or you can use the Vector class which has the same functionality as that of ArrayList, but its methods are synchronized

To synchronize the ArrayList, you can use.

  
List synList = java.util.Collections.synchronizedList(arrayList);  

Note this is will NOT return ArrayList instance. So you need to use List interface type after synchronizing.
