Now I want to make ArrayList and HashMap synchronized .Is there any way I can do the same without using Synchronized keyword ?

Sure:

Use a ConcurrentHashMap and any of the several List implementations in java.util.concurrent.
Use Collections.synchronizedMap and Collections.synchronizedList.

@dilshad: You mean like `Map map = Collections.synchronizedMap(new HashMap());`? – T.J. Crowder Mar 10 '15 at 11:21
no i mean about create own synchronized hashmap using some kind of login – dilshad Mar 10 '15 at 12:11
