In this tutorial we will see how we can use thesynchronizedkeyword in order to make sure that a specific portion of a Java application may only be accessed by a single thread at a given time. Intrinsic locks Before diving into synchronization in Java we must first understand intrinsic locks....
Example of Threading and Synchronization User Threads vs. System Threads Recursion Recursion Interview Questions Explanation of Recursion Can every recursive function be made iterative? Recursion Versus Iteration Permutations of A String Factorial Iterative and Non Recursive Find nth Fibonacci number Tail Re...
Java Lock API provides more visibility and options for locking, unlike synchronized where a thread might end up waiting indefinitely for the lock, we can use tryLock() to make sure thread waits for specific time only. Synchronization code is much cleaner and easy to maintain whereas with Lock ...
In this example we are usingCollections.synchronizedList()method. The important point to note here is that iterator should be in synchronized block in this type of synchronization as shown in the below example. packagebeginnersbook.com;importjava.util.ArrayList;importjava.util.Iterator;importjava.util...

Hashtable is slow due to added synchronization. HashMap is traversed by Iterator. Hashtable is traversed by Enumerator and Iterator. Iterator in HashMap is fail-fast. Enumerator in Hashtable is not fail-fast. HashMap inherits AbstractMap class. Hashtable inherits Dictionary class. 8. Conclusion ...
Java provides a utility for keeping things in sync. The atomic variables ensure synchronization. With multi-threading, we need to have the ability to ensure that our threads don't crash into each other or cause issues with data changes. ...

Some important interfaces and classes in Java Lock API are: Lock: This is the base interface for Lock API. It provides all the features of synchronized keyword with additional ways to create different Conditions for locking, providing timeout for thread to wait for lock. Some of the important...
