Concurrent collections in Java are designed with the goal of allowing many threads to access the same data in a synchronized manner. If you’re familiar with Java Collections, you’re probably aware that most Collection classes aren’t thread-safe by default. Take, for example, Java’s ArrayList, LinkedList, HashMap classes. We must manually make the collection thread-safe if…

Two methods with the same name but different parameters are permitted in Java, and these methods are referred to as overloaded methods. We must verify method names, which must be the same, and parameters, which must…
