A thread in Java is the path followed when executing a program. All Java programs have at least one thread, known as the main thread, which is created by theJava Virtual Machine(JVM) at the program’s start, whe
In Java, the synchronized keyword is used to provide mutually exclusive access to a shared resource. When a thread tries to execute a synchronized block of code, it will first acquire a lock on the object that the code is synchronized on. If another thread is already executing a synchronized...
When the object is created in Java, It has already a built-in lock that acts only when the object has a synchronized method code. There is only one lock per object. Class Testsynchronization{ Public synchronized void doStuff() { System.out.println(“synchronized”); } } The only method c...
So what we do is, instead of writing another class or method to read in the Employee’s bank account details, we directly reuse the existing Account class. In other words, we associate an Account object with the Employee so that we get the Employee’s bank account details. The above exam...
Communication is used to connect people through any digital device. The types of communication are asynchronous or synchronous. In synchronous communication, both parties reply at the same time.example: video call In asynchronous communication, the user has to wait for the reply.example: Email...

(),resourceis already initialized, which avoids the synchronization hit in the most common code path. DCL also averts the race condition by checkingresourcea second time inside the synchronized block; that ensures that only one thread will try to initializeresource. DCL seems like a clever ...
